Pretty cool. LG SmartScan mouse. Use it as a mouse. Use it as a scanner (for any document up to A3-size; 300dpi). It even does OCR. Save as PNG, BMP, JPEG, TIFF, PDF, XLS, or DOC. It runs for about $199.This would be good for laptops. Sure, you can take a picture using a cell phone, but then you have to send it to your email, log into your web email account, and download the photo. And you do this with a document, it's a photo, not an OCR document.
So .... if you have a laptop and can see yourself scanning stuff, this may be a viable option. And ... you can still use it as a mouse.
