Linux is not replacing Android tablets any time soon for casual use by non-techies. Especially on RISC-V, where not much software has been packaged to that architecture. Even ARM or X86 tablets don’t have much tablet-oriented software available. Most DEs are pretty shit at tablet style navigation.
It will gather dust, I guarantee it. Maybe someday Linux will be there, but it won’t be soon. And I’ve tried several times with several devices to make that happen.
