Guy Kawasaki -- a former Apple evangelist, author, entrepreneur, and founder of the Alltop.com web site (and the guy I once recommended as the successor to Steve Jobs -- but Guy wasn't interested) -- gave his "Revolution from the Rest of Us" today at the Macworld Expo.

His presentation looked at the current state of innovation and revolution in the tech market. He started out with tales of his early days at Apple, then went on to show five products and/or companies he really likes. There were also questions from the audience.

Square (http://www.squareup.com) showed its credit card payment for the iPhone. It's due in late spring or early summer.

Hearplanet (http://www.hearplanet.com/) talked about its self-titled app, a "talking tour guide for your iPhone." It sports: global coverage with "hundreds of thousands" of locations; additional enhanced content added daily; geolocation for instant info on what's nearby; and a search for almost anything in the world. It's location aware.
