The P2RD is not a replacement for the Optacon. The optacon's main advantage was that it used the human brain as its OCR engine. The P2RD is merely a portable scanner/OCR package. Though our scanners and current and always improving OCR packages are great, nothing can replace the human brain for text recognition. I keep an Optacon between to my scanner and computer keyboard. I scan in lots of recipe books, and could not edit them effectively without my Optacon. Context doesn't help when trying to determine what fraction of a teaspoon or cup is called for. Cookbooks and other technical manuals have to be exact. BTW, the optimization scan is truly the best thing to be developed for K1000. I absolutely love it!! Diane Bomar
