Jolicloud is one of the few operating systems that were made specifically for netbooks. With their success in making their OS work with the previous Atom CPUs, they are rolling up their sleeves once more in developing a version compatible with the VIA C7-M processor found in the HP 2133 and Everex Cloudbook as well as for the newly-released Intel Atom Pinetrail.
Jolicloud is different from your traditional OS because it focuses on web applications for most of the functions like email, office documents and messaging. It's a Linux-based distribution and looks similar to Ubuntu's Netbook Remix.
