They have some interesting features:
YouOS is an experiment in a new kind of computing platform. * Access from anywhere.
Create a document at an office computer, drive home, continue right from where you left off.
* Built-in sharing.
Instantly share music, documents and more with your buddies.
* An application community.
Everyone from professional software engineers to high school age programmers can participate at no cost. Choose from a growing list of over 540 released applications developed by our users.
I think this will probably go the way of the rest of the web app’s out there. I haven’t heard much about eyeOS after I posted about it like forever ago. Really, whats the point of running an OS in your browser, if you have to already run an OS to run the browser?
