Amazon needs a new business model for tablets, one that attracts big spenders rather than bargain hunters. ( If I were Amazon, I would start thinking about another operating system. Basing your entire tablet strategy on the platform of your most direct competitor probably isn't sustainable, either.)

Amazon can't win a tablet price war against Google because customers who don't buy a lot are expensive for Amazon to acquire, but free for Google.

Google's business model scales, but Amazon's doesn't.
