I am also in high school, and our school allows iPods, but not cell phones. Cell phones, if seen in the building, are taken, but may be used outside in a designated area during free periods only. They do not allow laptops, and that is completely reasonable in my opinion. Honestly, at school, I only need a computer two to three times per week, and while hand writing notes does get annoying after long periods of time, it is not that big of a pain. I agree with the no laptops policy for liability reasons as well as just the distractions. Many people I know, including myself, get distracted very easily, and the laptops just add to the distractions. I do not think your school is crazy, and I certainly don't think you are either. I think they made the right decision, and you would be intelligent to honor it.
The iPods, I think, are a bit excessive though. Really, phones can be used for cheating, but iPods (it is possible) are very difficult to use to cheat. I think the simple no-iPods-in-class rule my school has is very effective for stopping iPod-based cheating. I have never seen anyone at my school using an iPod in class, but if you go into the library or cafeteria at any time during the day, about 50-60% of kids are using one at any given time.
