I looked at Dino and another one mentioned here and they look dated. Windows 95 feel with better anti-aliasing, rounder corners, but same colors? Gtk 2 or something?
Looks like a standard GTK4 app to me. Whether or not that is to someone’s tastes is obviously subjective, but it uses the same design language as every other GTK app under the sun.
GTK apps always look out of place on Windows though. Looks far more sensible in its native environment (i.e. *nix running GNOME).
A small set-top box (essentially a Steam Deck with the screen, controls and batteries removed, and with components that don’t have the space restrictions that come with a mobile device) would still be an interesting proposition. Particularly if they partnered with the main video streaming services to port their apps across, and implemented Chromecast/AirPlay support.
I can see a market for it, as a “Chromecast and Apple TV competitor that also plays all your games”.
