The Psion series 5mx provided an impressive amount of portable computing power and ran on two AA batteries plus a coin-shaped memory backup battery.
I used mine to take notes in university classes because I couldn't afford a laptop and it worked great. The keyboard was a bit small, but big enough for touch typing. The built-in office programs made it a productivity beast and the compact flash slot meant I had a whopping 16 MB of storage which held several hundreds of documents and files.
After owning such a useful and charming little machine was sad to see Psion leave the hardware business and turn EPOC into Symbian.
