Using MP3 players for homework

Thinking back to the learning styles quiz, the use of MP3 players in the classroom or for homework makes sense for auditory learners. However, it could have disatrous results for a tactile or visual learner. I like the idea of this technology being offered as an option to students, but would hesitate to make it a mandatory part of the classroom. I am split 50/50 in my learning styles. I would definitely consider using an MP3 player for certain areas of coursework, but for extremely complicated material, I need to have it right in front of me on paper.
