How's that? My phone isn't 6", isn't geared towards holding with one hand while the other hand shovels Rice Krispies into my mouth, isn't terribly comfortable to read on compared to a Kindle, and requires touching the screen while I might be eating breakfast.
While some of the things might not be fit for the Kindle, the Kindle version should have a price to reflect that (and also reflect the lack of printing and delivery costs). Instead it's damn close to the price of the print edition, if not more.
Phone, Kindle, iPad, doesn't matter much to Amazon. The point is, you aren't going to pay $12/month for the Post. You could, but you won't. Instead, you're going to start paying $79 a year for Prime, which'll get you access to the Post on any device you want. And also instant video, so you can drop netflix. And free fast shipping. And that will make it so easy to buy other things from Amazon that you will. Often.
1-click was brilliant, but that's just one part of their overall strategy to remove absolutely every obstacle they can that might possibly come between your intention to buy and the action of doing so.
I think you're under the misconception that Amazon wants to sell Kindles. Amazon doesn't want to make money selling Kindles. They want everyone to have a Kindle.
That's why they have smartphone/tablet apps for iOS, Android, Windows (phone and 8) and even (gasp) Blackberry. They don't care what you use, they just want you to buy their stuff for it.
