You know, once I get some money my way I'm thinking I might get a cheap Asus and play around with Ubuntu or, if it exists by then, Paranoid Linux. I'm not ready to switch from Mac since I've been using it for almost 20 years but I like the idea of playing around with something different (and I guess I could always try x86 on there if I don't care for ubuntu, but from all the screens and skins I've seen-- it looks freakin' gorgeous.
