Look at this device, called Steam Deck store.steampowered.com/steamdeck
some youTube vids on it
It's almost a pc you can actually connect mouse and keyboard to, but it's super portable and good for some mobile game types, and it's relatively cheap.
I am not into much gaming other than CSGO so I am not gonna buy it, but If you have one how is it?? or would you like to have it??
yes, the name checks out but volvo making lot of money.
