I’ve been using the Steamdeck with Xreal glasses (1080p 60hz) since the release and can confirm the AMD 13 with Nreal glasses is a solid upgrade. I was getting MUCH BETTER graphics and frame rates while playing Warhammer: darktides, or Cyberpunk 2077.
Depends if you want a laptop or something in the form factor of a switch. The rest is irrelevant.
Actually there are handheld custom consoles built around the framework main board. So far I’ve seen 2, so it’s probably not something OP uses, still interesting projects.
