Thanks to KDE on the SD, I’ve switched my main DE on my desktop. Still have a soft spot for XFCE, but KDE Plasma on the SD was polished and was very “coherent”.
One thing the SD is missing for being a complete “serious” computer is printing support. I’m sure I could it installed, the SD is eminently hackable, but a Flatpak solution or a Steam default solution would really justify using a SD in Desktop mode for school and work.
I think the Windows thing is spot on. You’re going to be using a handheld gaming device for gaming mostly (if not entirely). You don’t need to run Excel.
I think the justification for Windows on a gaming device though is kernel level anti-cheat. The problem is that you are chasing a pretty select audience. People who will play one of those games on a handheld, and will also only buy a handheld that can pay those games. Also won’t install Windows on a Deck either.
An aside, I probably use Desktop mode more than average, and I have LibreOffice installed on my deck. Jokes on Microsoft though, I’ve been using Linux primarily for ages anyways, so I don’t even need Windows for that.
I’ve been complaining about printer support. It’s pretty much the last piece of the puzzle for a school focused SD.
