Yesterday, a Google executive spoke about the Android Market saying that the average G1 user has downloaded 14 applications of the now 200 available. Eric Chu, group marketing manager for the Android Mobile Platform, went on to say that the Android Marketplace is the "killer app" of the platform. Developers will be able to start charging for apps in the first quarter of 2009. The revenue will break 70/30. Of the 30 percent, Google will retain a small portion to cover credit card transaction costs and the remainder goes to the carrier. Perhaps this is what Ballmer was saying when he questioned the revenue model for Android.
