SaltyNZ:Nothing is free; data is no exception.
Yip, I agree that there's going to have to be some minimum APRU just to keep the layer 1 alive.
I think providers are going to have to put more and more effort in to educating users about data applications to grow the data usage and have users actually happy to pay for data and fell they're getting value.
"Calling Minutes" as a product, is something that I think will start to rocket down over the next year as people start to get traction on using smart phone applications and become aware of the existence of good ones that they can use on their phones.
I accept we may be a while away from data applications taking over, if my experience with this new 8150 is anything to go by. I managed to lock it up and make it reboot its OS this morning, so the apps clearly aren't rock solid yet.
