As already mentioned a couple of times, psion is still in business but they got out of the consumer market. They bought teklogix and only do industrial stuff these days (www.psion.com)
Having said that, I've read about this in a couple of places now and they apparently still provide support and accessories for the netBook and netBook pro so their actions do seem reasonable.
The netBook was their top of the line model at the time. They weren't really in the "organiser" class any more though as they distinctly resembled the netbooks of today. The psion series 7 was their flagship device in the former category, the netBook was a sub-notebook running Windows CE.
I would have really liked one at the time but they were astonishingly expensive.
