I like downloadable books. I started using them when I was working on my masters at Northern and did not have much time to read. They are just like books on tape or cd without the pain of hauling the cd player around. Before cars came equipped with built in mp3 players and adapters were cheap, the inability to listen to audiobooks with others was disappointing, but advancing technology has elimimated that problem.
Marley and Me is available for download, I have been meaning to read it but haven't had the time.
