"In an effort to further popularize Ubuntu Linux, Canonical has put a website in place where you can use a demo version of Ubuntu."
"You can browse files, you can use Unity Dash, you can experience Ubuntu Software Center, even install a few apps (they won’t be really installed), browse the File Manager and other such things. But that’s all."
