Many Cellphones have cameras. Wether you want it or not. While I had no problem taking 70,000 images with cheap Canon pocket cameras that then became twexus, I never really used the camera in the Motorola flip phone I am using right now.
I find it amazing how there are no phones that make use of the camera for themselves. Phone and camera share the power source, that’s about it. When I want to call somebody that is not in the address book I have to read the number and then type it. Not a big deal. True. But the camera in the phone could do that for me, right? Either trying to OCR a humanly readable number, or -slightly more involved- read a special barcode that could mean all sorts of other things as well.
