I had, and still mostly have a number of similar tools though never a Psion. My HP 95LX is currently on display in a museum! My first was a Philips Velo, then the HP, followed by a couple of iPaqs (Compaq then HP). The serial port on the iPaq was useful for running diagnostics when I was working overseas in the middle of a desert or in the arctic. Saved getting a laptop out and booting it up. The only difficulty was the stuff I was working on used a bizzare baud rate (10,400) so the people who created the software to drive the serial port had to do some clever stuff to make it work.
