Take a look at Microsoft’s Office Live Workspace. It is a free online service that let’s users store up to 5GB of files online for anytime, anywhere access. Right now it can be plugged into Microsoft Office 2003 and 2007 (although it can be used as a stand-alone service too), meaning it only takes a few clicks to save files from your desktop to the cloud.
