Amazon has been hounding book publishers into signing deals that would prevent them from selling iPad books at below Kindle e-book prices, a set of rumors from within the industry claim. Having anticipated an Apple tablet since December, the online reseller has reportedly been trying to negotiate "most favored nation" details that would guarantee that no competitor would get a better price. The larger cut of royalties promised last month is now said to have been intended as an incentive to sign these deals.
