Ask HN: Should Amazon sell the kindle like the iphone?

I just thought of this: If Amazon would bundle the kindle with a contract that requires me to buy books for $20 (or similar) every month for 24 months and in return the device would be free, that would be awesome.

I think it would be a win for everybody: Amazon sells more kindles and more books, publishers sell more books and I get the device "for free" (Or at least I don't notice the price that much).

What do you think of this? Is it feasible?
