What's wrong with Linux on a properly supported laptop? (OS X also sucks on improperly supported laptops... much worse than Linux, in fact). I find GNOME 3, in particular, much more productive on a laptop than OS X.
I don't doubt your anectodes, but the idea that Linus uses OS X on his macbook air is hilarious (according to what he's said, he's a Fedora user, and has retired his MBA in favor of a Pixel).
Also, Linus Torvalds uses OS X on his macbook air.
