Also, the keyboard looks the exact same as the Psion 5's but the mechanism is much worse.
I followed pocket reform closely but the thickness of it, combined with the price, put me off. It’s not the same class of device as Psion, Gemini, or the UMPCs.
I have a Gemini. I love it and still use it. The keyboard remains world-class, best of breed in any pocket-sized device. The OS is dated but still works fine and connectivity to Dropbox, gDrive, OneDrive etc. is very handy and mostly missing from desktop Linux.
As a pocketable laptop replacement it is unequalled, for this writer.
Curious though, did the whole unit bounce, with the screen wobbling back and forward, when you typed?
I occasionally can't remember where a character is, but I tell myself it's where it would be on a Psion and 20th century muscle memory kicks in and I just hit that combo.
Found this random video on youtube. You can see it wobbling at 15 seconds, though mine was more accentuated. https://www.youtube.com/watch?v=opmb6jbeBY4
Psion's own hinge mech was far better, but PlanComp only licensed the keyboard, not the case. I proposed a fatter "pro" model with a bigger battery that was the same size, shape and form factor as the original, so it'd fit in original cases. I still have several.
I was shouted down by Americans whose internal airlines apparently have or had some stupid limit on the size of battery you can carry on board. In Europe any battery over a certain limit has to be carried in the cabin, so if it fails the crew can extinguish it.
The PinePhone with its keyboard addon should fix most if not all issues the Gemini PDA had, but it looked so similar I still couldn't bring myself to get the keyboard for it. Plus I don't like the layout at all.
MNT Pocket Reform seems very promising (but expensive). Good layout and reprogrammable keyboard. Not stuck on an old Android version.
