YouOS is an online operating system that gives you the basic capabilities of a desktop PC, all within a standard browser. The upside is that you can log in from any internet-connected device and have all your apps and files right there. The downside is, of course, that everything you do is stored on a server somewhere. Everyone you email, every site you visit, every file you edit, every image you look at; all recorded and stored for someone else’s perusal. GooglePC, which is soon to become reality, may look very much like this. With Gmail and Google Desktop and all the other Google goodies tied in, it could be very useful and efficient. But it’s Big Brother’s dream come true. I created an account just to play around with it, and it is pretty cool. But I wouldn’t trust anything more than the name of my cat to this idea.
