If this encourages Linux mobile development that would be massive.
Gnome
The GNOME Project is a free and open source desktop and computing platform for open platforms like Linux that strives to be an easy and elegant way to use your computer. GNOME software is developed openly and ethically by both individual contributors and corporate partners, and is distributed under the GNU General Public License.
I think the work in immutable Linux will apply nicely
As a tablet Linux user, this is really cool!
What's your hardware?
Unfortunately a Lenovo Chromebook Duet 5 on ARM with PostmarketOS.
Bought it for myself shortly before the first Linux-specific consumer tablets were released–which, as I said, is quite unfortunate, but I wanted to have a tablet for school/university.
Camera and the USB-C port (apart from charging, obviously) do not work at all. I'm using Gnome and have problems with both random crashed and stutters/low framerate, general performance is okay though.
Annoyingly, some apps were not available for ARM (Thunderbird as recent as last year and Signal Desktop is still not available).
Tried Fedora Silver blue for ARM as well (which did not work at all), as Alpine based PostmarketOS is quite annoying for general desktop use (some apps just won't work and it once broke completely after an update).
In conclusion: won't recommend until your heavy into fixing stuff yourself/going for quite the ride.
Nice to see, but its useless in my case.
