Engadget: The Jolicloud Jolibook. Oh yes, it's sounded like a made-up device ever since the pictures of it started to leak out, but the netbook centered around the Jolicloud Linux operating system is indeed a real product. So real that we've been using the Atom N550-powered system over the past few days. Sure, we've gotten looks in public because its cartoon-covered lid, but the £279 ($443) machine isn't meant for "grown-ups" -- it's intended for a younger set, or those between the ages of 15 and 25. You know, those that tend to live in the Cloud. So, does the netbook have appeal beyond the young'uns? And is the social, app-based Jolicloud 1.1 OS, which is built on Ubuntu and HTML 5, robust enough to take you away from Windows or another flavor of Linux?
