Compatibility isn't broken between XP to 7 ... only certain apps that used unofficial APIs. And for those you can use its "XP mode" (built on top of Virtual PC).
Personally I've had few problems with Win 7, granted I only use it on my home computer.
Apple breaks compatibility a lot more often, like every two years.
