Persona,
First off, congratulations to your daughter and you on her admission into Duke. The education at Duke is second to none, and the investment made today will pale significantly when compared to the rewards she will gain academically, personally and professionally.
I have to echo your sentiments on the widely held perception that Duke is an elitist school for rich kids. I just completed my first year in one of the professional programs at Duke, and would hardly consider myself well off. My program is made up of people from various backgrounds, personalities and levels of wealth, testament again to Duke's commitment to diversity.
I am not sure of the history behind Duke and Apple's association, but I simply have to vouch for the efforts of Tom W. (full name withheld for his safety, naturally). Tom is an undergraduate student and the president of the Duke MUG, and has been a tireless champion for the Mac cause. He has never failed to answer any of the questions I've had about my Mac computing experience, through the Mac listserv at school. If you've visited the Duke computer store, you would probably already have met him, if you haven't, you probably will.
I strongly believe that the marriage of education and technology is a wonderful union. I foresee the widespread use of thin-film e-books someday, with each class session's material being broadcast to each student's machine as they walk into the classroom. The shortage of qualified, quality teachers can also be addressed by technology, as satellite classrooms make their way from tertiary education into the halls of K-12 schools. I predict that the Duke-Apple iPod deal will have a greater impact and significance on the educational process than we realise today. Then your daughter can look back on her iPod experience and say that she was part of something revolutionary. The one thing that I think is missing from this whole deal is an iTalk for each iPod. After all, those freshmen will need a device to record the Cameron Crazies as the Blue Devils destroy every team that visits ;o) . All the best to your daughter, Persona.
