The screen on a PDA is just too small to act as a real input device. The transient state of the memory on a PDA just isn't well suited to investing time in typing up any real information.The keyboard works well for what it is, but isn't terribly practical. If it's really such an emergency, find a computer to borrow. If you are interested in the novelty, go for a full sized bluetooth keyboard. I felt like this thing was going to break as I typed.
