Zune HD Size Calculations

Josh Sorenson from Cruleworld's Lifestream, hit me up on Twitter and let me know he'd done some caculations - the Zune team is being tight-lipped on the specifications of the Zune HD, but assuming that the photos are accurate, with a known screen size we can figure out the size of the device itself. The big deal would seem to be the thickness - a mere 0.35 inches. For comparison's sake, the iPod Touch is 0.33 inches thick, so essentially the same. And that's really thin.
