Appearantly I'm the only one with a downloaded book..............of course mine are still in "reading" format. I've got Wizard of Oz (Or is it OZ???) on my PDA, and since thats so small, I cant stand the idea of reading it off that *shudders*
I can understand wanting to hear the book when you're driving, or if you're like me and reading in the car makes you car sick after a while, but that's what Book on Tape is for. I agree with everyone else here, it'll take up way too much space.
