Let me start off by saying that I'm not trying to "troll" but just stating the facts. I'm buying the iPad Air and own many Apple products. Simply stating my opinion.
Well priced? Yes, it has a 64-bit processor, i'll give you that. But, the Nexus 7 is nearly half the price with a better screen with more quality. (Yes, it's .9" bigger but I pretty sure it isn't worth an extra $200.) Yes, the app ecosystem is better, but again, is it really worth that extra $200?
Honestly, I thought Apple planned Retina with the $329 price point in mind (I thought that was expensive until I thought of this.) IMO, $329 is the sweet spot for the iPad Mini. You pay a little more for the ecosystem, the bigger screen and the overall experience. But an extra $70 for Retina is way too much.
Also, I feel that regular consumers will opt for the last generation iPad Mini as they often ask "It does basically the same thing right?" I don't think they will drop another $100 for a better screen and processor especially when they compare it with the Nexus 7 and other competitors (which they will, they aren't biased as we are.)
