I have an iPad so I can get all the apps (like banking and governments ID stuff), but other than that it's GrapheneOS and Linux. I only miss things that are put on only the closed platforms (iOS and Android). Other than that I experience clean minimalism all day. Bless Gnome, bless NixOS, Bless GrapheneOS. They just get out of my way on the road to being productive.
...Ok there is bliss... and the pain of having to use MS365 through the browser which "just doesn't work" [tm] (constant log-outs, you're logged out but you don't get an error until 5 minutes of wondering where chats are going, you're a guest in an org but that works 20% of the time in 20% of browsers, etc, etc , etc)
If the desktop-mode on GrapheneOS (Android 17) would have a bit less papercuts that would be a nice platform for my MS365 stuff, but is suffers from stuff like the keyboard taking half my ultra-wide in some apps, and poor window management. It's really is close to being a viable work env imho though. That'd be so cool... The dream since Ubuntu's Convergence...
