I've been playing more single player games. My PC has mostly been for multiplayer stuff with friends - Siege, Deep Rock etc. My Deck has opened up time to a load of Single Player things - AAA things like Spiderman, Control, Mad Max and indie stuff like Black Skylands.
Plus I had a load of work travel in the first part of this year. The Deck made hotel rooms much more pleasant!
I agree, it's a bit annoying. Maybe you could put it in desktop mode, and configure it to turn screen off but not go to sleep? It'll still do updates then.
