I don't have an issue with in-app put purchases, it's like the old try-before-you-buy model. I have have spent 100s of hours playing "robot wants kitty" (with in-app purchase called kitty connect to get user levels) and "Solomon's keep" with its addons. Both apps are free (and brilliant), with optinal paid add-ons that make the game even better. If it weren't for these two games (with addons), I most probably would have traded my iPhone in.
