It does look so 90's. But my first reaction is that it looks cool as hell. But then pretty much everything I thought looked cool when I was 15 still looks cool to me now. It's the stuff that kids today like that seems lame. My brother while complaining about today's movies or music or whatever once accidently summed up getting old and out-of-touch by saying "cool stuff isn't cool anymore." Or as Homer Simpson said "I haven't changed since high school and suddenly I'm uncool."
Unless this is just the beginning of Nintendo making clear plastic cool again. Then all us oldtimers can brag about how we were into it before it was cool.
Kind of funny that such a retro design is being used on the 2DS, you know, the stripped down 3DS you buy for little kids that weren't even born yet when this sort of design was hip.
