That's an interesting gizmo.
I do carry my zune with me. I have to say, turning pages of a book with a gloved hand can be difficult. The light from a led is kind of harsh for reading. I have found that it's kind of nice to watch a movie when i retire for the night. Plus it's easier to hold with a gloved hand. I work swing shift so going to bed early even when camping just does not happen. So some sort of entertainment is mandatory.
