Hello,
I'm also an Mac guy, taking care of about 50 mac workstations and servers. Personnaly own 5 running @ home + 2 PCs.
I use PCs mainly for gaming.
I just got my new DualCore Macbook Pro 17 and installed bootcamp and XP on it. God It has got to be the best PC notebook ever made!
First thing I did was to install GRAW on it... it runs flawlessly, very fluid... but did not played long... will apply the new patch and try a bit further.
So far, no instability in XP, everything is working great and performances are awesome.
Only thing I could ask more would be to be able to use virtualisation with bootcamp's XP installation instead of rebooting everytime I need access to XP. Only rebooting when I need pure performance... Something like that is coming with OSX 10.5...
