Craig James Johnston has been involved with technology since his high school days at Glenwood High in Durban, South Africa, when his school was given some Apple ][ Europluses. From that moment, technology captivated him and he has owned, supported, evangelized, and written about it.

Craig has been involved in designing and supporting large-scale enterprise networks with integrated email and directory services since 1989. He has held many different IT-related positions in his career ranging from sales support engineer to mobile architect for a 40,000-smartphone infrastructure at a large bank.

In addition to designing and supporting mobile computing environments, Craig cohosts the CrackBerry.com podcast as well as guest hosting on other podcasts, including iPhone and iPad Live podcasts. You can see Craig's previously published work in his book Professional BlackBerry, and many books in the My series, including books covering BlackBerry, Palm, Nexus, HTC, DROID, and Samsung devices.

Craig also enjoys high-horsepower, high-speed vehicles and tries very hard to keep to the speed limit while driving them. Originally from Durban, South Africa, Craig has lived in the United Kingdom, the San Francisco Bay Area, and New Jersey, where he now lives with his wife, Karen, and a couple of cats.

Craig would love to hear from you. Feel free to contact Craig about your experiences with My iMovie at http://www.CraigsBooks.info. All comments, suggestions, and feedback are welcome, including positive and negative.
