One problem is the full-screen window system we use, while it is desired for a set top box and a remote control, it's no good for a normal pc with keyboard/mouse. So the plan is that when you click 'computing' there is a button that switches to a 'normal' kde or gnome desktop with a normal window manager, where there will be an icon to switch back again. No ETA on that yet, though, sorry, we're pretty swamped at the moment.
