All Sega consoles except the 32x and none of their handhelds.
Mark III, Genesis, Saturn, and Dreamcast are some of the best designs in gaming history. Sega knew what great design was. As an added bonus, the consoles are a dream to fix/mod. Outstanding design through and through.
I'm not understanding any of the Vita/PS2 answers in here.
The Vita's just a gel capsule with buttons on it. It's just...there. Existing. Well, not anymore.
The Switch Lite looks basically the same. Does that make it one of the best console designs?
The PS2 always reminded me of our TV from the 80s with all the weird, dust collecting shelves/ridges on the front. I don't get it.
And if you've ever taken apart or tried to fix any model PS2 or the controllers, you've entered a special circle of hell. Poorly designed interior.
