Yeah I only am using it for games I have all backed up installers for. I just installed it and XP Pro tonight on the MBP in my avatar and it's not too bad expect for the fact the the screen can only be adjusted from about 10-50% brightness, and then it jumps to 100%. I downloaded the drivers ATI had on their website for the video along with Catalyst though so I can manually control brightness and gamma. Notably though, ATITool after installing this driver turns the screen backlight off when you open it... Otherwise it has been pretty good; the graphics performance is about the same or a little worse than my desktop w/ an AMD Athlon 2500+ @ 1.83ghz, 2.5GB of RAM, and a 256mb x1300pro w/ the expection being Quake 4 because it has a dual core optimization setting (ATItool on my desktop gave it an avg, FPS of 145, the MBP gets about 126, but hey, it's not bad for a 1" aluminum sandwhich!). Performance on Flatout 1 and 2 is also pretty good, though I think the Mac version of UT2k4 ran a hint better than the windows one under bootcamp. I bet the newer nvidia based MBPs would rock out on all of these games though!
On topic though, I hope Apple doesn't plan on making all of their bootcamp beta users reformat their XP/Vista installs to make it work on the full Leopard release. I know they mentioned the possibility of stuff getting messed up in their release notes, but still. I hope I just have to burn a new driver disk and run it!
