What's pretty clear from all the various Android market segmentation stats I've seen is that Android, by very nature of its design, attracts the majority of the "bottom dwellers" of the socioeconomic strata. When you are the default OS for anyone that wants to offer the cheapest product possible, that's just going to happen. So yes, when taken as a whole, the term "Android users" is rather misleading as there are those who chose premium Android devices, and those that chose el-cheapo models. Not sure I've seen any studies that do a better job of really breaking down the Android OS user demographic profiles, and every time someone dares mention the word "fragmentation" on this particular sub-forum, they get their head bit off by those who see this as attacking Android. But lets not confuse those people with the facts, ok?
I agree, haven't seen anything like this yet.
I said as much in my original post. That really depends on whether or not you equate "college degree" with "being smarter." But what's not open to debate is "college degree" = "higher lifetime earning potential." Even with the high unemployment and global recession, that hasn't changed with the possible exception of a few high-skill vocational trades. But even then, the adage applies: For every rule, there's an exception.

Here's some current data to chew on for you....

There are other studies out there, just have to look for them. But this is also why more developers write for the iOS platform than they do for Android. More disposable income = more lucrative market segment. It really doesn't matter how many units Android sells...it matters how many of those users spend money beyond the initial phone purchase.
Finally, while I've no study to back this up, common sense tells me that wealthier people often don't have as much time to spend "fiddling" with their devices. Hobbyists notwithstanding, they just want a device to do whatever they want it to do. So for many, "more features" translates to "more fiddling" which is the opposite of what they want to do. They don't mind spending a premium to have someone else do their fiddling for them. The "less fiddling" part of the iOS experience is a big draw there. As every Android user knows, you can't really mod an iOS device without jailbreaking, and even then, its limited relative to an out-of-the-box Android experience. But to the affluent, that's just a waste of time and time = money. The affluent will easily trade money for time....that point has been proven for a millenia.
