After messing with all three platforms for the past ten years or so, I have come to the following conclusions:
Linux - Very stable, but way too complicated for most (novice) users. People want to be able to plug in hardware and have it work, not plug it in, search the web for drivers, fiddle with the drivers, have the device do less than it does on other platforms, etc. Similar problem with software, you should be able to put in a disk and have it work. Which brings us to...
Apple - Almost as stable as Linux, and very easy for the novice. Everything that Linux isn't, the Apple platform is. Hardware, that which is designed for Apple, is totally plug and play. Ditto software. Apple's problem is in availability of hardware and software and the price thereof. It has gotten better, but there have still been instances with my clients where they complain that *something* isn't available for their Mac.
Windows - The compromise. Generally cheaper hardware and software than Apple. Drivers are not a problem like with Linux. Not as easy to use as Apple, but not as complex as Linux. Most hardware and software is easy to install and use, but vulnerability to viruses and spy-ware is a problem that requires a lot of attention on the part of the user.
My recommendations to my clients on buying a computer:
1. If you are a total novice (and cost is not a major factor) and just want to do specific tasks, i.e. e-mail, music, Internet, etc., Apple is the way to go. More expensive initially, but less likely to cause future headaches.
2. If money is tight, but you don't have time (or talent) to mess with your system, go Windows. Spend some extra money on a good security suite.
3. Linux is a good choice for those who want to tinker. If you have modest means and you have specific needs that Linux can meet - web browsing, e-mail, word processing, etc. - it is a good low cost choice.
All three platforms have their place and none is perfect for everyone. This "mine is better than yours" argument is silly. Different strokes for different folks. Deal with it.
Just curious--when do you last work in Linux?
Linux was too complicated for most users...in 1997.
It's much easier now.
You do have to be careful when buying hardware, although the hardware support is pretty good these days.
I can see an argument for home users to use Windows so they can just buy junk hardware and have it work half-way. But I can't see a reason to continue to use it for corporate desktops. It's just too expensive, both in licensing and upkeep.
I disagree a total novice will think he is invincible,
stat them off with WinXP and a good security suite, teach them early.
