Umm, Planet Computer's Gemini anyone? Easily the most heavily used & abused phone I've ever had. Still waiting for my (long overdue) Astro Slide to ship ...
The Astro Slide is shipping (mine arrived in mid-January!) but it's a little small for touch-typing -- what I'm after is a 65% or larger full-scale keyboard that packs down into something a bit larger than the Gemini/Cosmo/Astro, or their design predecessor the Psion Series 5.
