Basically outside of the steam deck all x86 devices are large and cost $1000. However, android gaming devices have a wide range of form factors (clamshell, dual screen, etc) ranging from $200-$800ish.
In my experience, support is nowhere near steam deck (maybe half, if that) and you aren't going to be playing many 3D games, but it's great for indie titles.
So if you're looking for a smaller form factor to play indie games (including some older/lightweight 3D games) on the cheaper side, the android handhelds are an interesting option.
I think another one that's worth adding is Infinity Train. It's targeted at a slightly younger audience, but is a great sci-fi animated show.
Each season follows its own characters with a little bit of overlap.
