I think the takeaway is that most game systems look trashy and cheap. Save for a few like the SFC, DC, PS2 Slim/Xbox One S.
Btw, the MD2 feels just as cheap and plasticky as the Model 1.
I think console designs fall into three broad design motifs
Statement design (where form does not really follow function)
Eg Atari VCS, Mega Drive, SuperGrafix, N64, PS2, PS3 (original)
Primarily function driven
PC Engine, Super Famicom, AV Famicom/NES top loader, PS1
Bland/nondescript - ie without context you can't even tell it's a console
Wii, Wii U, Xbox One
There are degrees within each. Eg for bland/nondescript, The Xbox One S has some small defining elements, wheras Wii/Wii U are aggressively nondescript.
And you have those that are in one category but have elements of another. Like the superb design of the Gamecube, which is kind of like the most recent Mac Pro design wise - it's such a function driven design that it
becomes a statement.
Some are a bad mixes of design categories. The original Xbox is broadly a basic PC box, but lathered with 'badass dudebro speed ridges'. Or the original 360 - it's primarily bland/nondescript but has the dumb curvature added to add an element of statement.
My favourite designs are ones that nail their chic. The Mark III and original Master System ooze 70s/early 80s futurism, the former looks like it could be a prop on a 70s sci-fi show. US/PAL NES is similar too, mid/late 80s sci-fi for that one. I already mentioned the Gamecube, and in a similar vein the original PC Engine is function to the point of statement - top tier engineering. Super Famicom nails the '90s Japanese edutainment' look.
I honestly don't think there has been a really good design for a home console since the Gamecube. All PS3s are pretty stupid. Wii/Wii U are nothing. The final 360 model, PS4 Slim and Xbox One S are decent but nothing special. Switch is pretty slick but is a hybrid. Most handhelds have been quite good though, with the exception of the DS Fat and original 3DS.
