And given some recent news about Valve working on an ARM emulator and funding Arch Linux to help them start supporting ARM as well they might be working towards that. Though if that is for the deck 2 or something else further in the future is yet to be seen.
The only other major thing for repairability/upgradability would be less glue on the battery and threaded inserts, which doesn’t add size.
The glue was reduced on later versions and especially on the OLED version which also got threaded inserts. So those are already done and I doubt the next version would regress in that regard.
This is irrelevant with Steam though. Steam offers a runtime with preconfigured versions of everything that is needed to give the devs a consistent environment for their games to run no matter how fragmented the linux install base might be. This runtime is also what proton uses for ship its different versions.
It is not just WINE. The Steam Linux Runtime is a stack of linux native libraries, binaries and tools designed to give game devs a consistent version of things to develop games against. Recently they moved this to be container based and I believe proton (which contains wine) is run inside this runtime as well.
The social aspect of going into a dark room to watch a screen in silence? Vs talking a joking around on voice chat?
I don’t see why this would help. More likely there are two different teams/people working on either side separately from each other. I bet the windows work involves a lot more work on Microsoft’s or the chip manufacturer’s side than valves.
Sounds like you just need to keep the data on your server and use samba or NFS and a network mount on the other devices.
