The Psion is MUCH bigger - if you want a PDA to pop in a pocket, the Palm might be a better choice.
That apart, the Psion is a far more serious piece of computing. It has a slide out keyboard that you can just about touch type on (unless you have huge hands); it has a much bigger display; it can use generic compactflash card memory (32mb for around UKP45); it comes with its own programing language so you could easily develop your own Apps; the word processor outputs MS Word compatible files; you can get handwriting recognition software if you want to use this in preference to the keyboard (Allegro).
If you are carrying a small bag with you, the Psion will not be noticed. I used to use mine in preference to lugging my laptop around.
