I can't blame you if you haven't been following the Department of Justice's suit against Apple and (originally) five other book publishers for price fixing in the eBook market. It's kind of arcane and weird, but it's an arcane and weird thing that may affect the entire electronic book market, and if you're the kind of book reader who looks at gamers flipping out about DRM that places unreasonable requirements on the user and thinks "there but for the grace of God go I," you might want to pay attention. Just in case.
