I'm evaluating various web based desktops. A web desktop is a desktop in the cloud. So far, I have found three that I like. Today's is iCloud by Xcerion. I'll have a lot more info after my beta login is approved but from the videos, it looks like iCloud is the most advanced of all the Cloud OSes that I have looked at this far.
Here is a quick 3 minute video showing how to use the iCloud day planner.
And here is a little bit longer demo (5 minutes) of the OS itself.
