I've been toying with the idea, yeah. Then I got my MacBook Pro stolen and used an old laptop replacement with Ubuntu while I was in the process of replacing it.

Long story short, there are a few things that I couldn't get over within a week: - CTRL-C rather than CMD-C is now a weird contorsion for my hand. - CTRL-C and CTRL-V can't be used for copying and pasting in the terminal. I understand why, but really couldn't get over it. - I think the UI is not polished enough to my likings. It's good, but still lacking. Visual differences and missing proper exposé are at the top of this list. - iPhone integration (disclaimer: I didn't try that hard.)

So I went back to OS X.
