I love my Steam Deck OLED and would only really consider an upgrade for things that improve the experience or reliability. Being able to run low and medium-graphics games locally and stream everything else from my PC with Remote Play is awesome.
I’d only want things like:
- Hall effect or TMR sticks and triggers
- Better battery life(but honestly it’s already great)
- 1080p, but not at the cost of horsepower or battery
- More CPU and GPU power is never a bad thing but I wouldn’t want it at the cost of battery
- Cooler and quieter(it gets warm and loud on Forza 5, TABS, Helldivers 2, etc)
- Thunderbolt with external GPU support on the dock
- More storage is always a good thing and 2230 SSDs pretty much top out at 2TB
- The Bluetooth is laggy but I dunno, Bluetooth just kinda always sucks
and bloody hell Valve put the god damn xone driver in your SteamOS so I can use my Xbox wireless receiver without installing the driver after every update
