Hmmm.. what is Spotlight? You put a photo of a person on your desktop and direct a spotlight off and on it, depending on whether you love or hate the person? The new leopard goes the additional step of voodoo-ing the effect on the real person and thrusts him/her into oblivion the minute you take the spotlight off???!! OOOhh, so exciting. I should just go in for a Mac and Leopard just for this!
Glad that the genre is catching on.
