For a sneak peek at the future of computing, go to YouOS and click “Try a Demo.” Your browser window turns into a desktop of its own, with sub-windows for e-mail, chat, and Web browsing. There are also links on the YouOS desktop for a sticky-notes program and a rich-text editor. But these programs aren’t on your hard drive—they’re running somewhere in the vast unknown Internet.
YouOS is the fledgling startup of four recent college grads with a bit of angel funding. Its simplicity makes it a great demo. Anyone who logs on can instantly spot the big idea: You don’t need Windows! You don’t even need a PC! You can login and work from anywhere using any gadget with a screen and a keyboard.
