I'm disabled. I basically can't leave my bed. A normal mouse and keyboard are awkward to use. This controller would be perfect for me.

I know this from using my Steam Deck all the time. But it's getting a bit heavy. With the Steam Controller I could have my display and controller independent of each other.

But I will miss the Steam Deck's easy zoom feature (holding it closer to my face) that aided my failing eyes. But both Steam and KDE have software solutions for that that I can hopefully map to the controller pretty comfortably.
