ScanR

Another service, again, recommended by Lifehacker. ScanR takes a pretty simple premise, basic OCR and detail recognition and makes it available to anyone. It means that, say you run into someone and they give you their business card, you can then take a photo with you camera-phone, email it off to the service and you get sent back an entry for your address-book. Similarly, you can just scan whiteboards or documents into searchable PDF files. Handiness.
