The new kid on the block is Google Drive. G-Drive gives you 5 GB of space that intregrates with Google Docs so all of your stuff is in one place. Just like Dropbox the G-Drive application make a folder right on you computer and you’ll just save your file there. There are Google Drive clients for Windows, Mac, Android and Chrome OS. Linux and iOS apps coming soon. The user interface for G-Drive is kind of unusual. The docs you create out of Google Docs will open in their native application. (Example: .doc file opens with MS Word.) There will also be Google documents (.gdoc). The native application for these docs is Google Docs. If you click on a Google doc your default browser will launch and open the document there in the browser.
