I think I'll always have PC for gaming, but I'm really becoming fond of OSX.
Besides, now that Macs are using Intel, you'll be able to run WinXP --unsupported. But since Macs are built with very specific chipsets and components, it will be a piece of cake for people to get Win XP running well on Apple hardware. You'll still get that last 2-3% of performance running straight out windows hardware though.
I miss my Mac Mini
I loaned it to my sister because she has been doing a lot of multimedia presentations at work, and I don't think I'll ever see it again.
