Good point. So where can we find a control of some sort? I thought of the apple store, but that would be too biased towards my intended results IMO.
So where do we find that happy medium while providing sustainable proof? Can it be done?
I don't think you could. For example, we would expect to find more kids and teens using ipods because they won't have data plans (can't afford, parents won't let, etc). That could give the false impression that most iphone users are like kids since it shares the same OS and app store.
