The hardware looks impressive but it worries me that the first photo is basically just showing off a bunch of emulators. Why not show off more legitimate ways of playing games on it? I personally have never used steam big picture mode but it feels like it would be a good fit.
At $80, and likely an ARM processor, emulators have a larger game library. Wine doesn't work on ARM, and there are relatively few open-source games that stand out.
You'll be delighted to hear that that's not entirely true - there is a Linux x86-on-ARM emulator Box86 [1] that allows you to run Wine apps [2]. While your expectations should be realistic, it's made to defer as much as possible to platform native implementations so there's a bunch of things you can run!
