This xerox product may come to market in 2006. Use a cameraphone to photograph a document, then server-based software does OCR and compression of a processed image.
I'd use it.
I suspect the cameraphone will need a 2mpix image and the ability to do near-focusing to be truly useful. So most of the cameraphones sold into the US market today won't work. (Korea gets all the good cameraphones.)
