Jolicloud's core is based on Ubuntu, even though it uses a unique graphical interface and integrates a large amount of web services to fulfill the most common tasks. For this purpose, it integrates Mozilla Prism into the system, a technology that allows us to use web applications in a way that is very similar to how desktop applications are used. At the same time, it is capable of launching Windows applications thanks to Wine.
This innovating operating system integrates features like the possibility to synchronize files on the cloud, or even to use social networks without having to open the browser. Its installation is really simple and occupies very little space, which is very good if we take into account that the computers it has been designed for don't normally have a lot of storage space.
All in all, Jolicloud is a really interesting operating system if you want your netbook to gain in usability without losing functions.
