The original iPod professor, Sussex universities Dr Michael Bull, is looking for more feedback from iPod users.
He has requested that Macworld readers who have purchased an iPod shuffle get in touch with him to answer questions.
Bull is also interested in talking to people who use their iPod when at work.
Other aspects of iPod use that interest Bull include those who use their iPod to listen to audio books, and those who listen to Podcasts.
Bull also told Macworld that he has almost finished compiling his book based on the experiences of iPod users worldwide. Some Macworld readers have already taken part in the research for this book.
The book will be called: Sound Moves: iPod Culture and Urban Experience and it will be published by
Routledge in a couple of months.
