i feel pretty good about apple taking 70 30 especially at the start. It has unlocked a massive economy of all these aps being built upon billions of moble devices in a way where it's safe and easy for consumers to get at them. All kinds of businesses have been built in theapsor that weren't possible previously. There is a clear benefit that comes from a security perspective. We're having apples sort of vet everything and having them sort of make sure that you feel confident in stalling stuff. And again, that benefit is not just from users knowing that their devices are safe but also developers too.
