A behemoth slate makes an awkward camcorder or point-and-shoot. So what to do with your tablet's camera? Get CamScanner HD and use it as a document scanner. This free app makes it easy to digitize paper documents, save them as PDF files in more than 10 sizes and share them via email. Alternatively, you can upload the files to Dropbox, Box.net, or Google Docs. The ad-supported free version has its shortcomings, however, including PDF files created with watermark, and a limitation of 50 documents and 10 pages per document. If you like the app, spend $5 for the full version, which removes these limitations.
