Ubuntu One is the only sync service facing up to Dropbox

There are numerous cloud services offering file synchronization between gadgets and personal computers, but Ubuntu One is the only service that comes on a near second place regarding multiplatform requirements.
Dropbox works on Windows, Mac and Linux, as well as Android and iOS. Well Ubuntu One also works on Windows and Linux, it just misses OSX. the mobile version is also available for Android and iOS so it’s a tie regarding the mobile.
However, Ubuntu One has integrated services like a music library and contact backup which add value to the overall solution.
Feel free to check Ubuntu One out.
