OK, so this is Android, but is harkens back to the glory days of Psion, classic Symbian, Communicators, the HTC 7 Pro(!), and much more. The Gemini was designed by the same guy who designed the Psion Series 5, back in 1996, so it's worth taking a look, at least. For my Phones Show, I've now reviewed the Gemini and I think many people will find my verdict of interest. It can run Android, Linux or Sailfish (currently), it can run at a wide variety of screen scalings, it has full travel keys and pretty modern phone internals.
