I have just returned from a ten-day family trip to Japan in which I brought an Apple iPhone along and want to share my experience. I purchased my 8GB iPhone as a “laptop replacement” so that we could travel as light as possible. The primary role of our iPhone was as a casual Internet and email device. The secondary role was as an entertainment device for my children while on the airplane. (You can run out of things to pass the time for a three year old and a six year old during a twelve-hour flight from New York to Tokyo.)
