OCR is bad
While the idea is a good one, the UI deviates from Apple standards and more importantly OCR is not very good.
I scanned magazine articles with black text on white background. The OCR always tried to create odd shaped selections changing normal paragraphs into columns or simply getting garbage as the OCR text. It would take as long to just retype the articles as it would to correct the errors in OCR.
