I have bought 3 switch consoles and i still want something like a steam deck because steam EOL'd their remote play box. I want something i can play PC games on on a TV that i can also take with me to boring things like waiting rooms. The switch screen (i have the original switch) is too tiny, and it's a very heavy console. Switch lites have even smaller screens, but they weigh much less - it is possible the controllers i use undocked are just heavier, but either way. The steam deck has a higher resolution screen, and i'm sure some devices have greater than FHD resolution with greater than 60FPS "refresh". That's kind of a big deal to my crappy eyes.
Right now i have a laptop connected to my TV to play steam games that support controllers. I'd much rather just have another USB-C to HDMI converter plugged in to a device designed nearly completely to play games.
A huge use case for me would be using wemod/cheatengine and in general steam workshop. The second biggest reason is shovelware. On the switch if i buy a game because it looks good, AFAIK i can't refund it if it's actually a garbage game. On steam, i've requested refunds after playing (some*) games for several days.
* mostly incremental/clicker/idle games, because they're designed to be crappy to start out, so 2 hours isn't even enough time to expose 1% of the content or gameplay.
The problem with 1080p and higher on mobile devices like that is that the chips available for these devices physically cannot give a good experience at that resolution. The main limitation is memory bandwidth. It works great at 720p. Anything higher and it starts to break down.
Citation: I own a steam deck and an ROG Ally. The Ally has the best controller on the market but it's hamstrung by the screen simply having too many pixels. Well, that and Windows.
