Those are a bit like Nokia N900, their Linux powered physical keyboard phone from 2009.
The n900 was amazing. The hardware, the OS all really good. Nokia could have kept that going and won a huge market share. No login, no account, no tracking, no surveillance. Just your phone. But Microsoft execs ran then into the ground then sold the corpse to Microsoft. The non-surveillance, open phone was lost.
I have a Gemini and have been very pleased with it and have supported the Cosmo too because I want to support them. I'm hoping that if they continue to make sales they'll continue to develop newer devices.
These projects aren't quite delivering your complete feature set but they're making the best go of it out of anyone I've seen.
