Correct me if I'm wrong here, but isn't OSX actually based on a BSD unix rather than linux, or at least thats what I'd thought for sometime, and infact what wikipedia claims.

Still, it is very nice though from my dabbling on parents macs they've bought recently.

I don't like that it isn't quite so easy to compile and install things as it is with linux, but then, there are a lot more apps available for osx with similar functionality to windows ones than there are for linux, so rock <-me->hard place, at least for that part anyway.
