Ubuntu One is the new cloud storage product from Canonical. It’s available to users of Ubuntu Linux, but there are also versions for Windows, Macintosh, Android and iOS. You can also use Ubuntu One on the Web. This service is still under development, and it shows. Some features that are commonly available in other cloud services either don’t exist or exist only in slightly unusual ways with Ubuntu One. For example, if you simply visit your files in the cloud and click on them, there’s no preview feature.
