No. Most people do not follow Apples release schedule like us here. They simply walk in and say I want an iPad. Most wont know the difference between a 3 and 4th gen.
I disagree with this. Those avg people you speak of walk in and want the cheapest solution. Most are not interested in the Apple price tag. Most Apple buyers know exactly what they want and whats available. People who buy Apple are very much connected with whats going on in the tech world.
