I have to admit after decades of being a Windows person I bought a MacBook Pro about 4 years ago. I bought a new laptop a few months ago (I asked for Windows 7) but I still use my old MacBook 99.99% of the time. I didn't like the MacBook at first but it seems to have grown on me - especially with less crap being put into my startup process stack eating CPU cycles.
I do admit that it does have an easy user compatibility. I don't know, I've always been a windows user, it'd be hard for me to completely convert over to apple.
