Well I’m not sure how long these guys will run their service for free, but I really like the service and if you’re a researcher or student it might even be worth a subscription fee. The service is called scanR and as long as you send them semi-decent photographs (2+ megapixel) of either your Whiteboard or Documents, they will generate and email you the PDF versions of those. I particularly like their Business Card scanR. Photo goes in, vCard information comes out. Check out their examples of Whiteboards, Documents and Business Cards. BTW, Qipit is another online service that does the same stuff (less the Business Card scanning). Personally I like (and use) scanR’s Business card scanning since I’m too lazy to type all the info into my addressbook, your mileage may vary.
