I switched to Apple a few months ago.
It does not live up to the hype at all.
It freezes just like Windows programs did.
The windows interface was much better in my opinion. I hate how things open in the Mac and the way you view folders is horrible because they do not save the view format you had it in.
As Rickair said, many things are no compatible. Windows can run on it but you have to get a store copy, not a copy that came with a computer. XP is no longer available for that.
If it had not come with an iTouch and printer for free it would have not been worth the extra money at all.
