so why hasn't Google enabled the screensaver in Chrome OS yet? Well, pressing CTRL+ALT+T and then typing "top" in the shell shows us why. The Chrome browser is eating up 100% CPU time just rendering the screensaver! That'll kill your 8 hour battery pretty quick. As cool as this screensaver is, I doubt we ever see it live. Everything we've seen in the Cr-48 shows Google is much more concerned with performance (battery and CPU) than it is with looking pretty. Turning off the screen saves both screen and battery life.
