I would have thought games would be the more difficult step since most people seem to use their "smart"phones as fashionable gameboys and you need a complicated system of in-app-purchases for getting kids to accidentally buy $100 dollars worth of "smurfberries" with their parents credit cards to finance the production of these games.
