Zune vs Ipod Classic; Better for books?
Which one of these would be better for eBooks? Sure, neither are used for books, so there will be converting on both.
Which one would be a better mp3/m4a player considering that I plan to do some reading on it? Both are the 80GB versions. Also, I have a broken iPod that I can use for a 10% discount on a new iPod (maybe the 160gb model?).
I’m using an Apple Macbook Pro, and have Windows XP SP3 installed using Bootcamp.
I think iPod
