It quickly became one of my favorite gaming consoles. The ability to play anywhere didn’t seem like a big deal until I could do it.
I have zero interest in being tied to a single spot like the traditional console experience now.
The Steam Deck is cool but I waste infinitely more time dicking around with it than the Switch, where it just works. The Switch is the best console I've ever owned.
Reboots take a noticeable length of time and could certainly be faster but they're almost entirely "oh there's a new version of the OS" for me.
I haven't had any problem with games crashing either.
Its native controllers largely Just Work, and it's easy to turn on turbofire or rearrange buttons to work better with Steam Input. When I connect it to the projector and pick up the PS4 controller I have attached to the dock that works fine too, someday I should really try to properly pair it so I can use it wirelessly, but I mostly just play it handheld.
I basically spend zero time futzing around with Proton unless I am trying to get some old PC game to run.
I spent a while fooling around with installing emulators when I first got it, but I never actually touch them in practice, that's the only time I've ever been outside of the Steam UI.
