Dave Johnson has been a tech journalist since the days of the Palm Pilot and Windows 95. He's the author of about three dozen books about tech, digital photography, small business, and robots, and he authored a children's book that was adapted into an interactive storybook. Dave started out in the Air Force, where he flew satellites (he's always happy to discuss orbital mechanics). He was also editor of Mobility Magazine and a frequent contributor to publications like PC World, Home Office Computing, CNET, and others. A serial podcaster, Dave's most recent projects include co-hosting Battlestar Recaptica and Protocol 1: A Travelers Podcast. In what little spare time he has left, he scuba dives and plays drums.
