Buy your books like you buy your music

At least that’s what VitalSource is hoping you’ll do: buy eBooks from them in the same way people buy music from the iTunes Music Store. James Duncan Davidson just finished the new version of their client application, which looks pretty nice.
I, for one, cannot get in to the whole eBook thing. I have a few PDF-based books that I use for reference material, and I’ve read Cory Doctorow’s books in electronic format, but the latter is really because I’m unemployed and have to do what I can on the cheap. I much prefer the dead-tree edition of literature still.
