Pen scan it

I always wondered why it is not possible to scan just a few sentences from a book. As there are some products on the market, I ordered such an IrisPen. It took only 15 minutes to convince me, that this device is largely useless – a cheap plastic pen with a flimpsy contact but rather rigid USB cable.
What I even did not consider that syllabicated words at the end of every line can not be recognized by any OCR. So scanned words will require a lot of editing – while it may be better to invest into a typing course using all your fingers, yea, yea.
