Things I miss on OSX do include third-button paste from the highlight buffer and, of course, the superior virtual desktops (though OSX had them until Apple decided to cancel 'em), and the window list in the top bar.
But none of those is as important as focus-follows-mouse. I really miss ffm.
On the other hand, I like having working power management and long battery life. And I like never spending a day figuring out driver regressions.
