After total nightmares with win98 I was reluctant to go to XP, but have been very pleased with XP so far. I found with 98 the more you installed the slower it got, and more unstable it got. Although XP is better, I'm starting to find my install running a bit sluggish lately. I am probably due for a fresh re-build to clean things up and regain some performance. I have tinkered with Linux and like how it's evolving, but it's just not there yet as a fully functional desktop (lacks many apps, gaming, etc). OSX is awesome and it's tragic that Microsoft was clever enough to beat them out of the global desktop market. I'd much rather see the world using OSX than XP, but oh well...
