Not really helpful, but eBay is always a good place.
Psion Teklogix still makes a palmtop called the NetBook. IIRC, the Psion 7 was just a little bit smaller than this. There's a good chance that these shan't be reasonably priced, though, and they run WinCE (yuck).
I haven't seen anything in the consumer market, though. Seems as though everybody is migrating to mobile phones for things of that nature.
