Happening Right NOW! At the TWIT Live Meet-Up at the InterContinental in San Francisco. I ran into Leo Laporte at Union Square - we talked for a few seconds. He invited me to the meet-up....AWESOME! Several hundred people crammed into this side room / bar. Either way.....good times!

I'm at MacWorld 2012 iWorld iFanEvent and the hit of the show so far for me is the DLP Pico Pocket Projector that connects to the back of an iPhone 4 / 4s and projects a diagonal image up to 50 inches. Sells for $230 and will be available at BrookStone.com in about two weeks if not sooner.
