steamdeck verified is a lie, I bought a steamdeck and tested 20 games. Lots of problems.
What kills Deck for me are the game launchers.
For me it was the lack of portability (it's a chunky beast), I just wasn't taking it anywhere because it takes up so much space in your bag. By comparison the switch with it's disconnecting controllers fits in my electronics bag along with a bunch of plugs, chargers and cables and hardly takes up any room, and weighs a decent amount less. Looking forward to a slimmer and narrower V2 though, if it ever materialises.
