Firstly, integration with other apps is great, esp. Evernote. The app takes you to a well-designed screen, where you can select notebook and tags very fast.
As for its recognition performance, Im surprised by the negative rev .s, Ive scanned hundreds of paragraphs/pages with this, and never fell under 90-95% at any point with printed PDFs, books and e-ink kindle screen. (Just following basic instructions, no lab-conditions here) Its attractively fast too. I only have problems if the background/text color is unusual (eg. Yellow on black) OR if its handwriting.
