Surprise -- little electronic pen thingies may not be the future of text input. As evidence, note that Logitech has just agreed to sell the division behind its io2 Digital Writing System to Destiny Wireless, a U.K. digital pen and paper specialist.
The io2 is an oversized ink pen with a tiny camera that captures your writing and can later convert it into digital characters, as long as you write on special gridded paper. Reviewers were generally less than enthusiastic about the spotty accuracy of the OCR system involved.
