I came across this site called YouOS which is an operating system designed to run within your web browser. It’s currently in its alpha stages so expect many changes in the future. Right now you have the ability to create a document at an office computer, drive home, continue right from where you left off, share music, documents and more with your buddies, and best of all its FREE! YouOS comes with built in software already, a simple web browser, file manager, shell prompt, instant messenger, rich text editor, chat, sticky note pad, rss readers. Check it out today, I think its pretty wild.
