Well, I'm partial to Macs as I've been a Mac user for the last ten years but now my newest computer is a Window Vista box and I just opened it up an hour ago. It's very fast compared to my Mac and my parent's PC.
Honest! I love OS X but hardware of MAC are ridiculous price. I have no choice stick with Windows XP cause tons of games and free software I can apply to fiddle around.
I enjoy using Linux, but I find I always go back to using Windows, especially when it involves gaming. I guess to be honest, I have never really tried to configure Wine.
A lot of people seem to jump onto the Linux bandwagon, because software is free. But, a lot of open source software that started life on Linux are ported to Windows. So, I guess for the average user, it seems there is little reason to use Linux as an alternative OS.
People also talk about stability. Yeah, I think Linux is stable, especially if I am to compare Linux with Windows 95. But, I think Windows has evolved into a stable OS, too.
