I know it doesn't work well for multi-displays, but I freakin' love Command Center on my laptop when I'm not near an auxiliary monitor... so they got something a little right at least.
It is nice, and I'll admit, full screen applications with command center are quite nice. Its great having a full screen terminal with tmux running, chrome, xcode, etc... I agree its one thing done right.
And then there is Finder... but at least I have the shell, if only I could keep Finder dead or at least not visually running I'd be happier.
From a brief stint using Xmonad, I just wish there was a way to switch between full screened apps without the animation.. If you assign a key and switch rapidly between say, a browser and a terminal, it can get a bit much sliding back and forth..
