A smartphone can be hampered by it's small screen and inability to have any touchscreen/handwritting recognition functions. So I got to thinking, why not have a bluetooth optical mouse pen? I know the current OS wouldn't work with this, but the Pocket PC OS might be able to be ported with the input device changed from touchscreen to pen.
Would anyone but me like this kind of functionality?
Second thought, a built in lazer "virtual" keyboard.
I know someone will say that voice recognition is just round the corner, but for either noisy environments, or where you don't want everyone listening in (or they don't want to hear you talking away) I can see handwriting recognition, and a "mouse pen" would work well.
