Try Stardock's Start8 utility and you'll see just how useless the Start screen is on a desktop. Start8 is just like a curated Start screen Start menu hybrid. It's a far better implementation than Microsoft's.
Sorry, but I still think Microsoft screwed up by putting a tablet interface on a desktop OS. If they just had spent a little more time on how exactly they planned to get Metro on the desktop, things could have really been great.
