Apple is clearly the "high end" platform: the devices are often considerably more expensive, and thus likely to be purchased by users with more disposable income, which implies they might be more willing/able to spend money on apps.

I personally prefer Android systems because phones/tablets are not worth much to me and I'm not willing to pay much. I bought my smartphone (no contract) for $50 (about the max I'd be willing to spend), and my tablet for $200 (also about the max I'd be willing to spend). If an app has a price-tag, I'm usually not interested. (Ads are ok, though).

So in that sense, I'm an ideal/average Android user. I didn't buy my devices to use apps, I bought them for cheap network connectivity on the go.

Apple users have a more app-centered model which leads to higher revenues. It's no surprise to me that app developers focus on Apple, and that's fine with me. My co-workers are always showing me the latest app they bought on their latest iPhone or iPad. When their equipment breaks, they expect (and indeed do) have it serviced. (If my equipment breaks, I'll throw it away and buy something similar; I have no expectation of service). They're the ideal Apple consumer.
