My husband surprised me with an iPod Touch this past Christmas. I had no idea there was such a thing until about Thanksgiving prior to that. I had no idea how much I would use or enjoy my iPod Touch. We both have actually. He originally got it for me to store recipes. I continue to find new uses.
I found some interesting apps while looking through these articles and videos. One was a mileage counter, something so practical yet something I'd never really think about "needing." The graphing calculator is one that will be helpful to students. Teachers or librarians can use the iTouch to share "words of the day" or "today in history" facts with students. Students can use it to access the Internet or watch videos besides the apps they'll want to add. The weather information and the maps are also convenient to have available with the touch of a screen.
Here is a video on how to add apps to your iPod Touch.
