Guys, I have the hated MacBook Air Rev. A, 1.6 80 Gb HDD. I currently have Windows XP Pro in Bootcamp (I needed mostly because I run some audio programs -e.g. SoundForge- that are windows-only). I want to try Win 7. Do you think the performance is going to be much worse? How about compatibility? I tried Vista once, but I found myself formatting the drive after a couple of days. Such an annoying operating system!
