Would love to know the % of iPhone buyers that are geeks like us, reading tech sites, and know everything coming out, compared to the % of iPhone buyers that have no clue, they just want a new iPhone, regardless if the iPhone5 was coming next month, because they wouldn't even know that.
There is a difference in the % of geeks who read tech sites and know everything coming out. Part of such geeks only care about owning a latest phone, regardless of whether they actually need the newest features or not. These are very little.
The other part of such geeks are not afraid of owning 'an outdated phone', for as long as it does all they want it to do. Just like the rest of iPhone buyers who are not geeks and don't know about the forthcoming updates. They make a decision to buy the phone according to their needs, not according to how their phone will compare to the phone of their neighbor.
