I used that same excuse to switch to Mac, but found that OS X really didn't "just work" and that there were tons of things that needed extensive configuration to get to work properly.
Now, I'm on a Chromebook Pixel, and I can say safely that it's the only computer I've EVER used that really lives up to the "just works" mantra. To top it off, it actually is Linux inside, so for someone like me who uses a Linux VM on OS X most of the time, all I have to do is install crouton, do startx and go with Gnome 3 (which is quite polished now).
