An analogy of Kindle vs. Ipad can be made is dedicated GPS devices vs. smart phones. I believe the current state of GPS is the future state of dedicated reading device.

Another analogy is dedicated scanners vs. multifunction machines.

For a minority of people, a dedicated device is preferred. But for the majority of people, a multi-function device is suffice. Amazon's kindle hardware afters the minority while Apple' Ipad afters the mass. Amazon can not rely on the minorities to keep updating their devices as their business model because there would be no growth.

As technology advances, the gap between dedicated devices and multi-function devices will shrink. We don't know what kind of screen technology Apple will bring to the Ipad in the next few years. It could be a retina/paper/book display. If it is close to or surpass e-ink, the game is over. I Think the author's view is correct.
