Yup: I used to use one of the older models for drafting rough text on the train on the way to various College annexes. Light, lasted months on a set of batteries, and mimicked a USB keyboard - cost me twenty quid off ebay. I left mine in a drawer when I left sometime in 2007. We had class sets of the newer Neo version shown here for SLDD students. I'm imagining tablets with onscreen keyboards and cheaper laptops have seen them off.
