RetroGaming

Technically neither a console nor a PC (in the IBM-compatible sense), but the Commodore PET has a certain kind of 70s futurism about it.

Note the integrated tape deck for all your storage needs.

The keyboard pictured, while interesting looking, is a complete POS. Later PETs had a more usable keyboard with a better layout.

Edit: I don't think that red button at the bottom right is stock. It's almost certainly a hardware reset button, which on the Commodore machines is typically done by shorting a couple pins on a user expansion port.

I like the woodgrain look, but I don't think the Atari 2600 is a very good example of it. Lots of audio equipment from the time does it better. Especially when combined with brushed aluminum or stainless steel.

Purple GameCubes are retro now, so I'll go with that as my favorite.

Console: Sega Dreamcast

PC: Any IBM beige box from the 90s

while not necessarily the prettiest console by any means but i always thought the Og xbox home menu went way harder than it needed to, now that's presentation!

The 2600 depicted in the article thumbnail, was absolutely a beauty in its native environment of the late 1970's:

The Mega Drive is the best looking retro console, I mean look at it

It just looks so sleek. For me, it was the future of gaming.

Vectrex, hands-down.

One more vote with OP. That Atari is a nice looking machine.

I'm a fan of how ENIAC really used the space

I'm very partial to the IMSAI 8080!

The Atari Portfolio (the one John Connors uses in Terminator 2) or the ST Book.

PC Engine. Not only does it look like a prop from the set of TNG, but it is delightfully tiny. The cartridges are little cards that you slot in the front. There is literally nothing bad about a PC Engine. (Except for maybe that it's only got one controller port)

Humm, for PCs I’d have to say iMac

For game consoles it’s a hard debate between the GameBoy Pocket or the GameBoy Micro. One is the essence of a GameBoy shrunken down to a power efficent and usable design. While the other is the smallest you can make a console while still having it usable.

Nintendo's GameCube. It's cubical. Cubical!

Is PS Vita a retro console? If so that.

The Sega Saturn, especially the Japan version:

Although I never owned this model myself, I recently picked up an 8bitdo replica (M30 bluetooth) of the Japan controller and it looks and feels great, although not strictly a direct copy of the original.

Remember having one of these at school in the late '70s / early '80s

Game Boy Advance. Actually all 3 variants (GBA, SP & Micro) are beautiful consoles.

Why does there have to be just one? So many consoles are awesomely designed and reflect their eras well. I’m partial to colecovision and the Intellivision II. The redesign of the intellivision had an entire suite of peripherals to match the new design, including a musical keyboard.
