The new desktop is built around "Ubuntu One,"a collection of backup, note and contact synchronization and file-sharing services integrated into the operating system, offering 2 Gigabytes of free storage and more by subscription.
The Firefox 3.5 browser and improved audio support are also part of the offering. GNOME 2.28 is the shipping desktop interface.
On the server side the situation is more cloudy, but in a good way with the addition of full support for Ubuntu Enterprise Cloud, from Eucalyptus Systems, that lets you create your own mini-cloud based on open source. The clouds feature host and guest virtualization under KVM and guest virtualization under Xen.
Most new features were previewed in April.
A complete online tour of the new desktop is already online. A list of supported netbooks is available, but the company is suggesting you pack a thumb drive with its Ubuntu Netbook Remix when you go to the store, just to make sure. Should make Friday at Fry's fun.
