Microsoft also demo'd this at CES 2008, take a looksie. I was already blown away by the "possibilities" from the commercial-like excerpt that they released before (see previous post & link). I must admit, the practical applications that they demonstrate here I didn't even think of. The wine at a restaurant thing was alluded through the previous commercial-preview. But for retail?! Omygoodness, genius marketting and creativity.
It is already starting to pop up in Sheraton hotels, I received an e-mail from the downtown Sheraton in Seattle, WA about how they have a Microsoft Surface in their fireside lounge and to come explore Seattle with it - it's set up to highlight tourist attractions in the area for guests. I can't wait to play with it.
Being sad is the same as giving up.
