Computer question: Does anyone know a product that..

Buy a Psion (series 5/5mx) organiser off Ebay. They go for around 35 at the moment, but are still the only thing I've found that a) has a decent keyboard, and b) fits in a jacket pocket. They're fairly old tech - about 10 years old now - but still do the job nicely. They even run off standard AA batteries, so you don't have to muck around with a charger. the software lets you drag stuff straight in to Word and Excel formats to work on later (or in my case, from Word to Psion so I can work in the pub.)
