Honestly? I think its horrible, along with the original iMac. I think the only macs and mac-a-likes I like the look of are the titanium iBooks...
I'd agree on iMacs (small CRT sucks) but what's wrong with the other cases from Apple? The new aluminium G5 looks terrific, the cube is cool, "the lamp" is, well, refreshingly different. Can't really fault their design people.
