Apple is going to start forcing content providers (such as Amazon) to stop providing links to their web pages inside of apps as a way to sell content. This is so Apple can get its 30% cut from all in-app transactions. Content providers have to agree to sell their products at equal prices in and outside of their apps, so they cannot just raise their prices 30% for Apple users.
I think this is great news for Android users. Developers will now be much more inclined to release apps for Android as opposed to the ipad.
