As I'm reading it, they're going to charge 15 cents per megabyte to deliver the <i>app itself</i> to the device.  That cost will be deducted from the app price, and the remainder is what will be split 70/30 with developers.  They cap over-the-air delivery at 10 meg.  Anything over that is downloaded to user's computer, then to kindle via usb.  Cumbersome.<p>So you could have up to $1.50 of the app price deducted for delivery fees.<p>Probably not going to settle in on a 99 cent price point...
