Today Ubuntu 8.10 Desktop Edition is available for free download and simultaneous Canonical Ltd. release Ubuntu 8.10 Server Edition. Ubuntu 8.10 Desktop Edition is designed for the pervasively connected digital lifestyle. With new 3G network support, users can move smoothly from wired and WiFi networks onto 3G cellphone networks while traveling. Ubuntu 8.10 is also built to be shared – users can start a quick "guest session" on the fly and let someone use their computer to surf the web or check email, while maintaining the security and integrity of their own data. And if that person really enjoys their brief session as an Ubuntu guest, they can put Ubuntu on any USB key and take it home to install on their own computer rather than having to burn a CD.
