Tech Q & A

A: I often get this question from people contemplating their next computer purchase. The fact of the matter is that you will almost always get more for your money performance-wise from a desktop. You will pay a premium for the mobility of a laptop. However, the answer to whether you should buy a laptop simply comes down to answering one question: do you need the mobility of a laptop?

While you will pay a premium for a laptop, the reality is that the difference in performance between a laptop and a desktop may be not appreciable for average use. Obviously, power-users who need the most performance out of a computer should opt for a desktop. But for the average user, most laptops of today will provide plenty of power. So if a user needs to use a computer away from their desk, then the obvious choice is a laptop.

It used to be that laptop users needed laptops because they needed a computer when away from their office or home. However, wireless technology has freed people from being tied to their desk and users are taking advantage by having their computers more accessible. It’s no surprise that laptop sales are growing much faster than desktop sales. Many laptops are being sold because users want to use them anywhere in their home or office, not just when on the road.

One reason NOT to get a laptop is if a user has limited desk space. I often have users tell me they want a laptop because they don’t want a big computer on their desk. If this is the ONLY reason a user wants a laptop (and not for mobility), then they should consider an all-in-one machine such as an iMac. The flat-panel design of today’s iMac do not take a lot of desk space, and as mentioned above, you will get more for your money.

Another common situation I run into is where a user thinks they need both a laptop and desktop. They want the larger screen along with external keyboard and mouse when at a desk. I strongly recommend AGAINST doing this. The primary reason is that keeping data synchronized between two computers quickly becomes a big hassle. Unless a user has strong computer skills, switching between computers and keeping data consistent between them can be overwhelming. The second reason not to do this is that it is usually cheaper to buy a laptop and docking setup with external monitor, keyboard, and mouse. This way, a user can use their laptop on the road and still feel like they are using a desktop at their desk, keeping their data safely on one computer.

A: It is true that you can buy a computer for around $500 or even less. This certainly seems like a good deal. For that price, it would seem that spending any money on repairs or maintenance of an old computer would be wasteful. And it is true that in some cases it does not make sense to spend money on an old computer. But there are several things that people do not consider that can make a strong case for keeping up an old computer.

Not all computers are created equal. Most of the time, very low-cost computers are underpowered, lack adequate RAM, or are built from low quality parts. An underpowered computer can provide a very frustrating user experience. This is especially true when considering Windows Vista. Additionally, those who have kids that play 3D games must be careful not to purchase a computer with a less powerful video card that what is already in their computer. The video card is often more important to the performance of 3D games than the processor. The bottom line is that just because a computer is new, does not necessarily mean that it will be a lot faster that the computer you have now.

Many people forget that the initial purchase price of a computer is only part of its total cost of ownership. The less expensive the computer, the higher the probability of hardware problems. Also, the more likely that it will require upgrades sooner. And one must consider what kind of monitor, if any, comes with a low-cost PC. Old monitors need replacing as well. So the seemingly low cost of a computer may be a lot more than at first glance.

Finally, many people do not consider the time and potential expense of transferring their data, software, and existing peripherals to a new computer. It can be technically challenging for average users to successfully transfer their data and software to a new computer. And again, when considering Windows Vista, older peripherals may not work very well. So many users who purchase new computers must pay a computer technician to setup the new computer, transfer their data and software, and setup their peripherals.

So to sum up, low-cost computers generally end up costing a lot more than their sticker price when considering total cost of ownership and additional services required. As well, poorly made computers can become frustrating experiences for owners. Given these considerations, it can often make sense to fix up an existing computer to get a few more years of useful service out of them.

A: The batteries in most battery backup units last between 3 – 5 years. In fact, some companies have their battery backup software warn users that the battery in their unit is over 3 years old. Given this information, obviously most people would think they need to replace their battery in about 3 to 4 years. However, my recommendation in most cases is actually for users not to replace the battery in battery backup units. Let me explain why.

The first reason is cost. Simply speaking, the cost of replacing a battery in a battery backup unit is almost always nearly the same price as just buying a new unit. Even if you are spending a little more for a brand new unit, the pace of technology improvements in the course of 3 – 5 years means that you will be getting a better overall unit by buying a new one.

Second, the purpose of a battery backup or surge protector is to absorb power problems so your computer doesn’t. Over time, these devices can be damaged or wear out. It would be a shame to spend money on a new battery only to have the unit fail soon after.

Finally, some batteries can be difficult to find replacements for and difficult to physically replace. Any savings in getting a new battery will probably be lost in the time involved finding a matching battery and then actually installing it.

So basically, the answer to when to replace your battery is never! Generally, no harm comes if the battery stops working (but be sure to replace it right away), so you can wait until the battery backup indicates that it is time to replace your battery and simply buy a new one. If you want to be proactive, wait about 4 years to purchase a new unit.

A: It’s funny how many variations of this question exist. Yes, Microsoft says they will stop shipping Windows XP after June 30th. Some people think that this means that Microsoft will no longer provide support for XP. Others think they will be forced to upgrade to Vista this summer or their computer will stop working. But most people have only heard little bits of this story and basically have no idea what to think. So let me set the story straight for you.

Microsoft says they will stop shipping Windows XP after June 30th. They could still change their mind, as there are many grassroots efforts trying to convince Microsoft otherwise. But let’s assume Microsoft will stick to their guns. What this means is that Microsoft will not ship XP to the distribution channel (wholesalers) or directly to customers. However, any copies of XP that are in stock in distribution or retail will still be available for purchase as long as that stock is available. Many distributors and retailers are planning on stockpiling copies of XP, so it could be very likely that Windows XP will be available for sale long after June 30th. And there are some loopholes for “system builders”, small companies who build computers for resale where they can continue to buy Windows XP through the end of the year. There are also other loopholes that apply mostly to businesses which I won’t go into here.

So June 30th may be the beginning of the end of Windows XP, but certainly nothing dramatic will happen on that date. Your computer with Windows XP WILL continue to work. You will NOT be forced to upgrade to Vista. Microsoft will simply stop shipping new Windows XP copies. Buying a new PC with Windows XP may become a little more challenging after June 30th, but it will still be possible.

Also, just because Microsoft will stop shipping Windows XP does not mean they are ending support for XP. Microsoft will continue to provide “mainstream” support for XP until April 2009. Then they will continue to provide “extended” support through April 2014. However, most people don’t get support directly from Microsoft anyway, so this is largely irrelevant. What is important is whether or not Microsoft will continue to release bug fixes and security patches. Microsoft’s plan is to continue to provide security updates through April of 2014. As far as “bug fixes”, that is left up to Microsoft’s discretion whether they will release fixes to the public after April of 2009. But some experts believe that because Service Pack 3 for Windows XP was just released very recently, that Microsoft may extend the timeframe in which they will continue to release bug fixes for XP with SP 3.

So bottom line is don’t worry … be happy! June 30th will pass us by and you and your computer will be no worse for the wear. As usual, please submit any technology questions you may have to me and your question may be featured in this newsletter!

A: In any particular real-world situation, many factors will weigh into this decision. But for sake of simplicity, let’s assume that you could feasibly do either a wired or wireless network. When set up properly, either a wired or wireless network should perform well for the majority of things that most people do on a network, especially when using the Internet. So really there’s no reason you couldn’t do both. However, if you are using a particular software to run your business, you should check with the developer of that application to see if they support the use of a wireless network.

Many programs, especially those that had their roots before wireless networks, depend on a very reliable network to work well. While wireless technology can be very reliable, wireless networks can suffer from interference. This interference can cause varying interruptions in network service. Most of the time, a user may never notice. However, particularly sensitive applications may not work well even with very minor interruptions. Again, you must consult your software’s developer to verify their recommendations. Ideally, you should do this before you purchase the software.

In some situations, wireless networking is a critical necessity. If this is your situation, you should seek out software that was designed to work over less reliable connections. The good news is that more and more developers are realizing that they need to design their software to work over “unreliable” networks such as the Internet. As they design their software to do this, the ability to use wireless networks for business software improves. As well, wireless technology continues to evolve. Newer devices are much better at managing interference and preventing network interruptions.

With all that being said, however, if it is feasible to wire your business, I suggest you do so, especially if you are starting a new business or moving to a new space. It is much easier to pre-wire a building during build-out or construction than to wait until you’ve moved in. By having your business wired, you have the flexibility to implement a wired network if desired. As the speed of wired networks improve, your business may one day need to take advantage of faster networking speeds. One tip: make sure you wire using “Category 6” cabling. This newer type of cabling (as compared to Category 5 or 5e) supports Gigabit Ethernet, which is up to 10 times as fast as the most common type of network today. Already, many new computers come with Gigabit networking built-in, so Gigabit networks may become more common sooner than later.

A: “System Restore” is a feature of Microsoft Windows XP and Vista which allows users to revert a core set of specified system and application files to a previous state. In some cases, a System Restore can allow a malfunctioning Windows computer to return to proper operation. However, it seems like many people think System Restore is a nearly-magical method of fixing any Windows problem. The reality is that System Restore is only capable of fixing certain types of problems. In fact, System Restore could cause problems if improperly used. Think of System Restore as a “shotgun” approach to system troubleshooting. It is possible to throw the baby out with the bath water using System Restore.

For example, a System Restore can partially uninstall recently installed software programs, rendering them inoperable but difficult to completely uninstall or reinstall. It is also possible to “restore” viruses or spyware that had been previously removed. Also, Some people think System Restore will restore data files that may have become corrupted. System restore is not designed to backup user data files, so if the problem is with a user’s data, System Restore won’t help. And in certain cases, System Restore can actually cause users to lose files from their desktops.

Having the knowledge I have, I much prefer a “surgical” approach to computer problem resolution. This way I am more comfortable in the solution I provide, knowing exactly what I did and minimizing the chance of “collateral damage” – i.e. causing other problems in the course of fixing one. However, I realize that most people don’t have the technical knowledge I have and in certain cases a System Restore could be a useful tool in an urgent situation. Obviously, I recommend that users seek qualified technical help whenever feasible. But if for some reason using a technical professional is not possible, then the question becomes when could a System Restore be used?

First, I recommend that a user has a solid backup system in place, unless the problematic computer stores no important data. With this being said, if the problems just recently started and the user can establish a fairly certain sequence of events that appeared to trigger the problem, then a System Restore has a higher probability of success with a minimized chance of collateral damage. The user should try the most recent restore point prior to the beginning of the problems. If the restore operation does not work, the user can undo the restore operation by running the System Restore utility and choosing “Undo My Last Restoration”. The user can then try another System Restore point a little further back in time, if desired.

But let me reiterate, System Restore is not a “precision” troubleshooting tool. If you really want to ensure that your computer is in proper operation, I do recommend the services of a qualified technical professional. Certainly feel free to contact me if your computer is having trouble and I’ll do my best to help you out.

A: Internet telephone services such as these use a technology commonly called “Voice over Internet Protocol”, or VoIP. Basically, they convert voice into digital data that is carried over the Internet then converted back into voice. VoIP can be implemented in many different ways, such as using VoIP inside a company’s private phone system. However, for purposes of this question, we’ll talk about using VoIP technology as a replacement for “regular” phone service, otherwise known as “plain old telephone service” or POTS for short.

Vonage and similar companies are VoIP services that position themselves as POTS replacements. These services use your existing broadband Internet service. Often, the companies provide equipment that connects to your home or office network, as well as to your existing POTS equipment. So basically once the service is set up, you will continue to use your old phones just as you did before. Instead of your voice traveling over the local phone company’s system, your voice is converted to Internet traffic and rides over your Internet provider’s network. Generally, these companies position their services as being cheaper than service from a regular phone company.

Skype and similar software provide VoIP services by utilizing your computer to make the voice to digital conversion. Often, the user you would be calling will have the same software on their computer. Usually, the companies that provide the software will not charge you if the person on the other end also uses the same software. They will only charge you if you are calling someone with a regular phone.

Finally, many Internet providers are offering phone services, which while they may not advertise them as such, are based on VoIP technologies. Basically, these services are very similar to Vonage-type services, but they are simply bundled with the Internet providers data service.

As far as the voice quality of these services, reports are many and varied. Some people have had very good experiences with these services. Others have not. Generally, the biggest factor in the quality of these services is the reliability of the underlying Internet service.

The only way to know if a particular service will work in your particular situation is to test it out. My advice is to test the particular service you are interested in before completely committing yourself to that service. Most services will provide at least a one month free trial. If you really feel a VoIP service will be beneficial to you and you’d like to ensure that your network is optimized to support VoIP, please let me know. I’d be happy to help you out.

A: This is one of the most common questions I get. The answer is not so simple. When asking if a certain service is “better”, some people are asking if one is faster than the other. Others are asking about reliability. Others want to know about price. All three questions may have different answers depending on the person asking it.

To start, understand that cable Internet and DSL Internet are virtually the same service. They both provide “always-on”, high-speed Internet service to your home or business. In fact, the technologies are so similar, that much of the equipment that cable and DSL providers use behind the scenes is the same. The main difference is that one service is delivered by the cable company lines, the other delivered by the phone company lines. To the user, once the service gets to their computer, it is basically the same – fast Internet.

Which type of service is more reliable? This really depends on your neighborhood. I know clients that rarely have any problems with their cable Internet or DSL service. I know other clients that cancelled their service with either cable or DSL because they had too many problems. In other instances, as the respective companies upgraded their infrastructures in various areas, service quality has improved. The only way to really know if a certain service is reliable in your area is to ask your neighbors. What service do they have, how long have they had it, and how often do they have problems?

So which service is faster? This depends when and where you ask it. As of the writing of the article, in my area Charter Communications offers cable Internet service up to 10 Mbps. AT&T offers DSL up to 6 Mbps. So at this time, the fastest Internet service available in my area is cable. However, that hasn’t always been the case and it may not be the case in all areas. In the future, it is likely that DSL providers will introduce faster services, probably leapfrogging cable at some point. Then cable providers will probably offer faster service again and so on.

The more important question is not who has the fastest Internet, but who has the best value for your money. Does it really matter if cable provides 10 Mbps service if you are only interested in about 1 Mbps service? Also, what conditions are attached to any advertised rates? Often, advertised rates are only 3 or 6 month promotions. Other times, to qualify for advertised rates, customers must also subscribe to other services. Another consideration is independent DSL providers. There are many companies that offer DSL service independent of the local phone company. Their rates may be better and/or they may offer better customer service. The bottom line is to thoroughly check all the details of any rate plans to make sure that you are actually getting the speed you want at the rate you want. Also, since companies change their rate plans all the time, periodically check to see if you qualify for faster or cheaper service. Companies generally don’t change your plan unless you ask them to – even if they are offering cheaper or faster services.

After all this being said, keep in mind what I first stated: both services are virtually the same once they get to your computer. As long as you are getting reliable service at price and speed that is satisfactory to you, then it really doesn’t matter much whether the service is coming over a cable line or phone line.

A: Leopard is the marketing name for the recently released Macintosh Operating System 10.5 (otherwise known as Mac OS 10.5 or Mac OS X 10.5). It replaces Mac OS X 10.4, commonly known as Tiger, which had been the current Mac OS for about two-and-a-half years. Apple claims that Leopard has over 300 new features. You can see the full list, which is well worth a read, by clicking here. While many of the features counted in this number are minor, there are a few major features that are important to note. But before we get started, you may be wondering why Apple names the Mac OS X versions after big cats?

To keep a long story short, almost all companies give code names to new products in development. Apple started giving big cat code names to each major revision of the Mac OS, starting with Mac OS X 10.0. Usually, these code names are only used internally within a company, as was the case with Mac OS X 10.0 (Cheetah) and Mac OS X 10.1 (Puma). However, with Mac OS X 10.2, Apple’s marketing team started publicly using the code name, Jaguar, and the name stuck. After that, Apple just kept using the cat names to promote each new version. Mac OS X 10.3 was Panther, 10.4 Tiger, and 10.5 Leopard. FYI, Apple has already registered Lynx and Cougar as trademarks.

So getting back on track, what features of Leopard set it apart from the previous Mac OS as well as Windows? One very nice feature is Quick Look. This allows a user to quickly view a document without needing to open the program first. Quick Look works even if a user does not have the software to open the file. Obviously, this can be very handy. While the user won’t be able to print the file, at least they will be able to view it. This can also be a time saving feature, especially for users with older Macs. Currently, Quick Look can allow users to look at the contents of these common file formats: PDF, Microsoft Word, Excel, PowerPoint, OpenDocument (OpenOffice), most graphic formats, most video formats, as well as many other formats. Additionally, Quick Look can be expanded by 3rd party plug-ins so even more file formats will be Quick Look compatible.

The other noteworthy feature is what Apple calls Time Machine. Time Machine is easy-to-use automatic backup software that comes as part of Leopard (and hence part of all new Macs). Literally, all you need to do is connect an external hard drive to your Mac, answer yes when Time Machine asks if you want to use that drive as a backup, and Time Machine takes care of the rest. Backups are performed automatically in the background. You don’t need to set a schedule or tell Time Machine to manually start a backup. If the external hard drive is removed from the computer, Time Machine automatically resumes the backup when it is reconnected. This makes Time Machine work very well with laptops. Including such easy-to-use backup software with Leopard means that Mac users as a whole will have their data better protected.

To wrap up, while many of the 300 new features are minor, as a whole they really do improve the Mac OS, making it generally easier and more intuitive. Again, take a look at the new features, as some may be of interest to you.

For all things Apple, Marcel is your expert.

A: My philosophy on anti-virus software is that it should be as unintrusive as possible to the user and have as little impact as possible on the performance of the computer. Many anti-virus softwares annoy their users with frequent warnings and bog down the computers they run on because they require excessive amounts of RAM and other system resources.

Given this criteria, I recommend Trend Micro Internet Security. I have found that this software is the least intrusive software of the 3 major anti-virus softwares (Norton and McAfee being the other two). Year after year, Trend Micro Internet Security also seems to require fewer system resources than the other softwares, resulting in much less impact on system performance. If you have a business with 5 or more computers, I also recommend Trend Micro’s Client/Server Security Suite, which is their software for businesses.

One other very nice feature of this software is that they make it very easy to stay current. While other softwares make pricing distinctions between “upgrading” and “re-subscribing”, Trend Micro only charges for yearly subscriptions. As long as a user is current, they can upgrade to the latest Trend Micro version at any time.

While the 2007 version of Trend Micro Internet Security required quite a bit more RAM than I would have liked, the recently released 2008 version returns to form with a much slimmer RAM footprint. Combined with the other improvements to the 2008 version, I am highly recommending that all my clients upgrade to this version.
