Just got a steam deck and immediately checked out the desktop mode, and I was somewhat surprised to see KDE and pacman as opposed to GNOME and apt, I have nothing against the former though a strong preference for the latter, anyone know why Volvo went in this direction?
Another point for KDE might be that it works much better on a small screen that may be partially obscured by an overlaid keyboard. I used Bazzite Gnome for a while on the Steam Deck and I much preferred Plasma on there after switching back, despite using Gnome on my main system.
