Yeah the PSP Go was a bloody stupid idea, sacrificing physical media entirely.
2DS sucked as well; I'm not opposed to cutting out 3D to reduce costs, but getting rid of the clamshell form factor and making it a slanted slab instead was a misstep.
The 360 Slim was a winner, in that it solved the system's biggest problem while (reliability) while being visually decent.
While I'm not a fan of the system as a whole the Xbox One S was a visual upgrade over the base model, and even snuck in some minor performance improvements, so it deserves a shoutout.
