Ubuntu is a complete Linux-based operating system, freely available with both community and professional support. It works on laptops, desktops and servers.

But the beta label implies a bit more stability as well as a few new enhancements. Here are new features in this latest version of Ubuntu
Desktop 3D effects
Compiz Fusion is enabled by default and will bring 3D desktop visual effects that improve the usability and visual appeal of the system. Ubuntu 7.10 automatically detects whether the hardware is capable of running compiz; if not, it falls back to normal desktop.
Fast user switching
It is now possible to easily switch between user sessions without the inconvenience of entering your username or password numerous times, a time-saver on computers shared by multiple users.
Fully automatic printer installation
Printers are now automatically configured by merely plugging them in and turning them on. Printer setup cannot get any easier!
