I'm usually one of the dissentig voices when I say this, but I think the GUI in OS X looks pretty horrible, and for me it works even worse then it looks. Most of it strikes me as eye-candy just for the sake of eye-candy, with little consideration for actual function. It's the one system that even though I know how to use it, I just get angry every time I have to use it for some reason or another. It doesn't work at all for my way of doing work, and I'm pretty sure if I won/were gifted a brand new Mac, the first thing I'd be inclined to do is format the drive and install something that works a bit more sanely for me.
