Note that Planet Computers are currently developing the Cosmo Communicator, which kinda-sorta resembles the Pro1X layout, except with the (vastly superior) Psion-descended keyboard design of the earlier PC machines: https://www.indiegogo.com/projects/astro-slide-5g-transformer/ https://www.indiegogo.com/projects/astro-slide-5g-transforme... As it's their third iteration I'm reasonably confident that this isn't vapourware and will ship some time after June (it was originally promised for March but COVID19 has hit everyone -- along with chip shortages). For those who haven't used a Gemini PDA or a Cosmo Communicator, the Planet Computers smartphones have a keyboard descended from the late 1990s Psion Series 5 PDA, which actually has reasonable travel and tactile feedback rather than the chiclet style keys of the Nokia N900 or Blackberry or Pro1X. This means the Astro Slide is inevitably going to be a bit fatter than the Pro1X, but be easier to type on (and has a similar dual-mode use case, with a big touchscreen and a slide-out keyboard). The Astro Slide also promises 5G connectivity, 8Gb of RAM, and support for Linux OSs as well as Android.
