I don't have time to type out notes on a handheld device; but, I'll voice record lengthy notes and transcribe them later. Otherwise, I always have a pen and 3"x5" ruled index cards on me in my shirt pockets. These can also be carried in an easy access belt pouch made for similar sized electronic devices. Written notes allow for personal shorthand. Index cards can be organized, reorganized, extracted, added, and even grouped on a scanner to print out a page of selected notes all without tedious transcribing. Stick-on tabs turn index cards into dividers for filing. It works for me.
