A laptop does not support attached controllers for hand-holding. Seems pretty obvious.

I cannot hold my hands in the air indefinitely. Even completely empty my arms will get tired after a few short minutes, much less several hours. My Steam Deck gets held on my lap or on a table or something like that.

OneXPlayer has something similar that I actually considered buying (but ultimately didn’t for several reasons) that includes a keyboard and (laptop) trackpad and a pen. If I can buy 1 device that can do both handheld gaming and also laptop productivity, I can save a whole lot of money…
