Optical Character Recognition is processor intensive, but we've got more power and more room with the newer smartphones to pull it off. Use the camera to take a snap of text, have the OCR system decode it. If my Palm Phone could read my handwriting (like my old Apple Newton could circa 1993), then I'm sure with a little processing power (and maybe a SIM card) it could translate my own handwritten text into real text. A scanner is a camera, so the better the camera's (my iPhone has 2.0 megapixel camera) resolution, the better the scan. I'm sure they'll upgrade this as things move along technologically. It's only a matter of time and engineering...:)
