That's a really good point. Whilst the goal of providing a good OS on low-end smartphones aimed at lower income economies sounds noble (is noble, in fact) it doesn't work commercially for developers because nobody will have the spare cash to buy their wares. It's a real shame and it wasn't something that was immediately obvious to me at the time because I was very new to mobile development. Now of course I've experienced the same frustrations as every other mobile dev and realised that it's just not worth targeting anything but the top quartile. That is, unless it's a corporate app and you have a large number of lower end devices in the field that you don't plan on replacing before your app is deployed.
