Linux: We've featured one way to mount your Google Docs library as a drive in Windows, but blogger Martin Owens has created an application to do the same in Ubuntu, so you can edit and save to Google Docs from your desktop.
It's a very simple, almost more proof-of-concept app than anything else, but it does the trick quite nicely. Now instead of having to open up your browser and use Google Docs to edit or upload documents, you can edit them in your favourite word processor and save them to a virtual drive in Nautilus. Any documents you save there will automatically show up in Google Docs, and you can drag any documents off the drive to save them locally on your computer. Just install the program and head over to Applications > Accessories > Google Docs Connection to mount the drive. You'll have to enter your username and password every time, but overall it's a small price to pay if you're not a fan of Google's web app. Hit the link to try it out.
Google Doc Mount is a free download, Ubuntu 10.04 only.
