In a few weeks we will be releasing the ajaxOS, a fully functional AJAX-aware operating system. The most exciting feature in ajaxOS is the ability to store to a remote server, with full access to file navigation on this remote server as well as your computer’s hard disk. As easily as you save and open documents on your local machine, you will be able to do so on our secure servers.
It looks interesting, but I’m not sure what kind of advantages there’d be with an OS that understands Ajax. There’s some teasers on the functionality that could have promise (ability to save files to a virtual storage, and be integrated directly with it) - only time will tell though. Keep an eye out for this release soon!
