PixelSense should be in my living room right now....no excuse for it not to be.

Something like it probably will be one of these days, only it won't be Microsoft and then we'll all wonder how they dropped the ball on something they had a 5-7 year lead on.  In this case, they had both the idea and the technical execution... epic fail on getting the product out there to a place where economies of scale could bring the price down far enough to make it viable for the consumers.
