Joli OS was at the beginning built on top of Ubuntu Netbook Edition, and as with that Linux distribution, was tweaked for netbooks and other computers with limited disk storage,memory, and screen size. Joli OS is now built on top of Ubuntu with a customized kernel.
Joli OS 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 but also works on a very large number of other devices, up to 10 years old: laptops, desktops and even tablets.
