tootbrute@hellomiakoda has one. It seems the best option. We need open hardware. Maybe if enough of these things out in the wild, then postmarketOS might support it.

@tootbrute @bluegreenandfree @Lydie I have the FLX1, not the FLX1-s. The FLX1 suffers from OOM.
Other than that, it's decent. The FLX1s has more ram and might not suffer such severe OOM issues.
