i-Tunes University:Benificial?

i-Tunes University is a brand new function developed by Apple and is starting to be expiremented by universities all over the country (most recently Stanford University. The basis behind it is that lectures for classes will be recorded onto students i-pods for them to listen to at home. Now some people may find this to be a waste of time and money: please hear the arguments because the studies for this expirement may suprise you.
A recent study has been conducted involving students and their grade comparisons between using and not using i-Tunes for their classes. A study was conducted by the University of Stanford with Physics students. Some where given i-pods with podcast lectures while others were not. Surprisingly, students who had acces to the lectures at all times averaged a 77 on their exams while the other students only averaged D's. Now these results may not be the case under circumstances with different schools, types of students, etc., but they are not anything to just toss under the rug.

When looking at it myself, I believe that this is something that can definatly improve my life as both a student and teacher in the fututre. It would be good for students who miss class because although they miss the "physical" aspect of the learning process, they can still learn the material and have access to the lecture at all times. Even if you were attending the class, this is a chance to go back to the lecture and keep your brain fresh with the information that was given by the proffessor. Of course there are some disadvantages such as student perhaps using the i-pod for other uses during class time, but I would have no problem with limiting the content just for the sole purpose of the learning and not for music. I would also think this would be good for my future students as well. I may not always be around to help them, so having them listen to my lecture could be beneficial for them as well.
