Have you seen the GPD Win 1, 2, and Mini? The 1 and 2 are older and no longer in production, but are decently thin clamshells, with a single screen instead of dual, and a thumb-type-capable keyboard. The GPD win mini is thicker but with more up-to-date specs, supposedly better than the steam deck. I don’t think it’s available yet though.
a thin DS style clamshell with an 8 inch screen, dual track pads and extra face buttons instead of back buttons

I’ve thought about them, though I think id want more space for the buttons… like a 3ds without a bottom screen
