Jolicloud is built on top of Ubuntu 9.04 (Jaunty) Netbook Edition, and as with that Linux distribution, is tweaked for netbooks and other computers with limited disk storage, memory, and screen size.
Jolicloud was designed for easy installation, with Wi-Fi, Bluetooth, and 3G modem support all included. The operating system supports all the major netbooks, including models from Asus, Acer, Dell, HP, MSI, Samsung and Sony. Jolicloud claims the OS supports 98% of netbooks with out-of-the-box compatibility.
Version 1.0 of the operating system incorporates a user interface built primarily with HTML5 that includes an application launcher, a library of compatible applications with one-click installation and removal, a display of all machines associated with a user account, and a social activity stream that enables users to compare installed applications. The launcher displays only those applications supported in the library, but the identical configuration can be viewed from any machine running Jolicloud. Account management is available from any computer with an HTML5-compatible browser. Jolicloud's HTML5 implementation is through Google's Chromium, which serves as middleware for Web rendering.
