Craig Grannell has this to say about the restrictions now in place for the App Store:

This is about getting Kindle off of iOS, because it competes with iBooks. Thing is, Kindle being booted off iOS won’t make people switch to iBooks—it’ll make people buy Kindles. And time people are using their Kindles is time they’re not using their iPads and iPhones, potentially reducing the likelihood of them making purchases.

I disagree, I think that if that is truly what Apple wanted they would have bundled iBooks into iOS and then rejected the Kindle app under the dubious ‘duplicating existing functions’ title. Apple clearly has easier means to booting Kindle — this is a play for more money, not for a monopoly situation.
