Let me go on record that I love the PCE + CD, but its aesthetic design is severly lacking. In fact, I'd so far as to say that the reason I enjoy the the suitcase is because it was 100% utilitarian design -- utility, not style, was the driving force behind the suitcase's aesthetic.
That said, our discussion is about design for design's sake, and the PCE + CD lacks "style" (you know what I mean).
I think I have to be a loser and repeat myself:
The TG-16 console has great aesthetics (compared to the hideous, goofy Genesis/MegaDrive and the ugly, awkward SNES). Sure, TG-16 was wide, but it was still slim with a low-profile (the cover on the bus stays snugly in place for me). I think TG-16 (sans logo) would look contemporary alongside today's electronics. Can you say this of any other console? Now, the TurboBooster (Plus) doubled the depth of the console and consequently stripped away the elgance of the core TG-16 design, but, on the other hand, I always liked the aesthetics of the TG-16 + TG-CD combo. It's quirky, but it is actually a lot cleaner (aesthetically) and more streamlined than the PCE suitcase combo, IMO. Sure, this might not be saying much (since the suitcase looks as if it was "slapped together"), but I offer TG-CD as evidence of the neat, uniquely North Amercian aesthetic that too few folks appreciate. The Genesis stacked atop a Sega-CD forms a big ugly brick... tell me, is the TG-CD really so bad?
For comparison: In my humble opinion, the NES had a great utilitarian design and the SMS was the most "futuristic-looking" console design of the 80's (not a bad thing, in my book, since I dig the odd angles and sharp corners and shiny surfaces of the SMS).
I stand by my earlier statements:
1) The shell on the back of the TG-16 stays snugly in place for me. I've handled at least two dozen TG-16 consoles over the years.
2) The Sega-CD + Genesis was a huge FUGLY brick.
3) The Genesis / MegaDrive always looked like a gawdy, goofy toy.
4) In fact, no North American console has aged well... but the TG-16 is the least fugly of them all!
