alt Hacker NewsNEC made some great looking consoles, in Japan. The PC Engine, the PC Engine Shuttle, the IFU-30 unit "briefcase", and the SuperGrafx. I think console design peaked with the SuperGrafx.
In the back of my mind, I have the idea that US regulations required extra shielding that the Japanese model lacked. Maybe this isn't the case. Maybe some American marketer decided it was just too cute or too small.
I think the redesign of the NES shell for the North American market was largely for vanity reasons, wasn't it? Entertainment system instead of computer, grey plastic instead of beige, front loading instead of top, long cartridges that were supposed to look like VCR tapes instead of toys.
