I can tell you that while people keep buying them, there are those that still see no real use for an iPod. Because they are an "electronic device", their use is frowned upon during take-off and landing in planes.
We did, however, put Kyle's iPod to good use last month. You see, Kyle auditioned for a part with lines in the school spring play at his school. Since Kyle is busy but can memorize well, he didn't know his part as well as the teacher would have liked. To help with this problem, Marj and I got his script, read lines into some recording software (Garage Band in this case) and had him load it onto his iPod. Running through his lines with the lines we recorded (everything around his), he was able to memorize them quite quickly.
Wonder if that would work for Scripture memory!
