It’s actually so great. It isn’t the most powerful system but you can play most of the top games from the past decade at 60 fps and the more recent unoptimized games could potentially get a patch via proton to make them enjoyable before official updates (elden ring was an example of this).

The basic user can enjoy most of games that don’t suck on steam without any effort or issues. Couch and bed gaming friendly, fairly easy to pack with included carry case, decent battery life, and will work as a desktop in a pinch with a usbc dock/hub.

With willingness to use the Linux desktop mode you can do a bunch of extra stuff:

protonup via built in app store (discover) to get proton-ge for largely increased game compatibility and performance, ymmv by game. It also has steam tinker launcher which enables much more tweaking to the benefit of modding and cheat/trainers among other things. (As a working adult I totally support cheats in single player games since ain’t nobody got time for grinding)

cryotools for more performance improvements

heroic, lutris, bottles, probably others. stores other than steam, games not from stores, programs that aren’t even games, etc.

emudeck for basically every emulator mostly preconfigured. BYOB, that means bring your own baby bios. Yuzu pineapple etc will require further intervention.

steam deck refresh rate unlock for what it says. under and overclock. mine flickers at 30fps/30hz but my brother’s doesn’t. 70fps/70hz works for me too on games the system has enough power for.

steamos btrfs for more game storage via compression. I recommend only on the microsd. The odd game that has mods that mysteriously bug out usually works by making the correctly located and named folder for it on the ext4 system drive and toggling case folding before installing normally (can only toggle empty folders). I actually just delete and redownload because I have a steam cache server. btrfs doesn’t have case folding.

If you aren’t scared of opening it up, or drive reimaging, and can get an authentic and reasonably priced 2230 nvme, I recommend getting the base model and putting in the larger nvme. Just slide the wrapper off the old one and put it on the new one. Also get the gulikit hall effect sticks off AliExpress. It’s basically necessary for jank ass minigame inputs like FF7R darts… They just released the new version that supports both stick types. My brother has the 512 and the screen difference is negligible, and nonexistent if you put a tempered glass screen protector which I can see no reason not to do.

tl;dr: great as is, so much extra great stuff if you are a Linux nut or willing to follow guides.
