Upload, View, and Share PDFs with Google Docs
Already adept with Word, Excel, and PowerPoint files, Google Docs has added support for PDFs. You can upload them from your PC, view them online, search inside them, and share them with others.
Other than that, PDF functionality is pretty basic. For the moment, file size is limited to 10MB, and you can't e-mail PDFs to your Google Docs account like you can word-processor documents and presentations. Still, Google Docs tends to take baby steps, so I'm sure more PDF goodness is just around the corner. [via Google Operating System]
