While I don't care much about video game hardware appearance, I gotta vote for the Wii. Despite the motion control gimmick and low specs, the Wii has a clean, angular design. It doesn't look too different from a cable box or DVD player.
I'm very nostalgic for the GameCube design, even if it looks like a lunchbox. It's nice and compact.
Gotta say the NES and SNES are the weak links. Their Japanese designs were better, as were their late-life replacement designs.
