Linux

Thankfully Valve has done a ton of work to minimize that divide, although even the two checkboxes you have to tick on most desktop Linux installs to automatically fire off Windows games under Proton instead to filtering out only native Linux games are completely unnecessary and kind of annoying.

As for SteamOS, people need to get their story straight. Either it's just Big Picture running by default over Linux, and then it's just like having Steam Big Picture autolaunch on boot on a Windows handheld, or it's a fantastic consolized UI that is the killer app that makes the Deck so much better than any other handheld.

Honestly, I lean towards the latter. SteamOS is great, compatibility aside. But if you do want to use it as a full Linux install then you have the same limitations you have on any Windows handheld, which kind of defeats the point.
