Looks like it'd be a nice augment to the usual keyboard & mouse/trackpad setup (& to a touchscreen, too).

For some tasks (e.g. changing to a diff browser tab five across from the current one) I can imagine that pointing at it would be the quickest and easiest way to switch to it.

I can imagine it'd get a bit tiring if you were relying on it too exclusively.
