Call 911, I’m having a handy attack! George turned me on to a wonderful iPhone app called JotNot Scanner Pro. Snap a photo of a document or page in a book or magazine, and the app converts it to a PDF. And the quality is very good, almost the same result you’d get with a flat-bed scanner.
I’ve been snapping pix of text and saving the images since I got the iPhone. But having it converted to PDF on the fly is the bee’s knees (mixed insect metaphors).
