Loved that thing! Batteries lasted forever and the LCD was perfect for the job of being focused. My hands are almost too big to touch type on it so notes often needed editing when transferred to a desktop. Typing on it is kind of like writing with Graffiti on a Palm, it takes some practice and then all of a sudden you're pretty good at it.

If you liked the Psion you might like its successor the Gemini from Planet Computers (https://store.planetcom.co.uk/products/gemini-pda-1). Same awesome keyboard.
