Less than 1% of users of steam have bought a steamdeck? I would have thought more but I don’t know how many users steam has in the first place.

No, although cool, my deck works great still for what I use it for. I’ll get a few more years out of it hopefully then make a switch. I’m also planning on getting the switch 2 (should it look like a good value) so that will eat up my allowance I get from my wife for such things.
