Surface computing

I'm sure I'm behind the curve on this one, but so what. Watch this 2 minute video and be amazed. No more keyboard; no more mouse. Way cool and way expensive - about 5 to 10k - but for commercial use only. Retail consumers will have to wait about 4 more years. My only question is 'how often does it crash?'
No more keyboards... - The most amazing bloopers are here
