What if you could type with your finger. Like if you make a letter "P" with your finger on the screen, a letter P comes up. That would be cool.
That was done with the Newton, then Palm & many others. Maybe the finger will work better than a stylus. On my iPod Touch I use a stylus for all of my typing. It works faster & is much more accurate for me.
With all of the years since the Newton came out & now these handhelds have much more power. Maybe this sort of text reconition would be a use for some of it.
