For those users who have been looking for an online desktop this is probably the most attractive one I've seen so far. It's called Jooce and can be found at www.jooce.com.
The system feels like a normal desktop environment and uses the applications on your host OS to open files such as .doc. What it does offer though is online storage and a place to view photos, videos and share files and folders. To call it web storage with a nice face would be grossly understating what this application can do. Apparently however it is memory hungry and so struggles on low end machines but even with that this is worth a look.
