Bill Ray in The Register suggests that Amazon's use of a 3G telephony network rather than WiFi is a whole new experience for users. Books and magazines have the potential of becoming interactive.

A book could be updated daily, or chapters added when the author has time - readers might subscribe to a book rather than buying it outright."
