The real sparks may start to fly when the price wars collide with vendor lock-in. It's not clear what kind of DRM we'll see for iBooks. They've mentioned using ePub, but it's not clear if they'll go with Adobe's DRM, like the Nook, or some version of their own. It will also be interesting to see if Apple allows the iPhone/iTouch Kindle app on the iPad.
