Congrats on the new gear! I have a 2-in-1 Dell laptop and a Surface Go 2, both running Debian 13. In laptop mode, I really like GNOME, in tablet mode it’s… fine. The biggest problem is the GNOME OSK, which honestly is not great. It frequently needs to be manually triggered (instead of automatically opening when clicking in a text-entry zone) and it’s missing just about every modifier key unless you’re in terminal mode. And GNOME (in its infinite wisdom), decided that the user shouldn’t have the choice of when to put the keyboard in terminal mode. There is one extension, https://extensions.gnome.org/extension/5949/gjs-osk/, which helps, but it just duplicates a hardware keyboard virtually instead of providing a fully featured mobile-style keyboard.

On my tablet I use Phosh, which can be installed on top of GNOME and provides a mobile-forward UI and a much better OSK. The Phosh-tablet metapackage in Debian 13 doesn’t take up much disk space and, IMHO, will give you a much better touch experience than vanilla GNOME (if you don’t mind switching back and forth depending on whether you are in tablet mode or laptop mode). Other than the inconvenience of switching back and forth, the only bug I’ve noticed is that maximize/minimize/close buttons need to be restored when switching from Phosh back to GNOME Shell.
