My new 2010 15" i7 is on route to me and I'm trying to decide which version of Windows I want to bootcamp with. On my mid 2008 pro I used Windows XP because I only had 2gb of ram. But since my new pro has 4 gigs of ram i would be losing out of some memory since xp can only register 3.5gbs. So I was wondering if anyone has experienced using xp 64 on the new macbooks, or if the bootcamp drivers will even work with that operating system since it didn't really have any support. I would rather use xp than 7 since i have a desktop that i use as a media center/ gaming pc already, and the extras that 7 offers arent necessary on my pro. Thanks
