I would never have considered gaming on Linux until the Steam Deck came out. When reviews said it's actually awesome, I became convinced to try it. Basically, the deck pushed me over the edge to ditch Windows altogether. So suck on that, Satya! No wonder MS is trying so hard to stop other OEMs from making Linux handhelds.
I'll use snaps if I HAVE to, ex Telegram. AppImages just seem like the same prob with grabbing binaries, in terms of updates. I might jump on the FlatPak train if I didn't like apt so much. Man, OSX and brew really is so much better then this shit, just works and is always up to date.
I'm using OSX for work and Homebrew is really slow there too. Honestly though that's really my only complaint. That, and some aesthetic yank caused by it being a bunch of shell and ruby scripts in a trench coat, but that's not an objective thing.
For real. I've been a pretty steady Linux user all my adult life and gaming was barely ever an option unless the game was built to run in Linux. When proton came out I gave it a shot and was blown away.
