Wii is going for the Mac-type minimalist look. As a Mac user (one of the few on VGChartz, I'd wager to guess) I thus prefer the Wii. I'm a fan of miminalist art (a la Donald Judd) in general, though.
I feel like such looks are much better than hulking anti-art monstrosity look. The SNES had a great look too--kind of like Brutalist architecture done in plastic.
I share a 3-bedroom apartment with two roommates. We keep to ourselves, so my TV and consoles are in my room. Thus the Wii fits a lot better in the minimal space of my room much more than any other console would.
I'd say Wii>360>PS3. At least the 360 is going for design. The PS3 seems to me to just be a big hunk of plastic. Surely a design that allows more stacking or ability to fit in places would have been better, no?
My consoles and the fates they suffered:
Atari 7800 (Sold), Intellivision (Thrown out), Gameboy (Lost), Super Nintendo (Stolen), Super Nintendo (2nd copy) (Thrown out by mother), Nintendo 64 (Still own), Super Nintendo (3rd copy) (Still own), Wii (Sold)
A more detailed history appears on my profile.
