Ok.. first question I cant seem to answer: What has windows not stolen and poorly implemented? Sitting here on vista, the obvious few: Start button search.. doesn't even work fully yet... one of the simplest things too! Gadgets. Seen the dashboard? nuff said. Flip 3d. Expose on os x is so much better.. you dont have to hold windows+tab to keep it open, expose will stay open until you click... and gives you window labels.. Perhaps a better question: What has windows stolen that was implemented effectivly?
