I got a new Macbook Pro 13" last week and installed win 7 build 7100 on it the second day I had it. Mac had been my preferred OS up to this, but windows 7 is hands down superior in my opinion. I think it installed in about 20 minutes, almost all the right drivers installed by default and the only real problem that I still have is that the fans don't seem to turn on when they should... hopefully that will be resolved by the time it comes out of beta. Anyway It's by very far the best operating system microsoft has come out with to date and I can't wait until 2012 or so when my company will switch to it from XP.
