You're comparing two things that happen on a much different scale.
The percentage of old/crippled Android phones running old OS versions is much higher on Android. Apple doesn't sell iOS devices with a 3 years old OS, and unless you have data to contradict that, app sales to iPhone 4 users are a more than probably a lot higher than to the $75 Android phone users you're describing. Developers who develop for both platform must know that.
The whole point of this is that the Android global marketshare majority doesn't mean much, and that the iOS apps ecosystem is still better overall than on Android, for both devs and users.
I don't think I am doing that at all. People buying older Android hardware are not the people that should be targeted by developers because they are not buying their devices for the latest, greatest apps. It's quite simple. For the record, the iPhone 4 is much more hardware-wise than these $50 handsets we speak of.
Some quick Googling showed that Android activations just about double iOS activations on a daily basis (some numbers put it closer to nearly tripling, but they are based on less sound statistical data). For some quick and simple math, that is 50 activations of iOS versus 100 activations on Android. If we take 75% of Android number, we have 25Android vs 50 iOS, speaking for latest OS upgrades. There is no denying that iOS outnumbers Android, but the numbers aren't the rdiculously abysmal numbers we are seeing some people spin. The sheer number of Android devices out there makes up for a lot of the disparity. If you need more information, just look at the sales numbers of Android flagships versus, say iPhone 5. Again, the iPhone 5 outsells any one Android phone (but together we are seeing a LOT of top end Android devices go out there). These are the comparisons that nobody (well, Apple, i their Keynote) is making, because it doesn't sound as awesome.
Market share should never be looked at as the sole metric for deciding platform success. This isn't a new thing with smartphones. It's been this way since we had the term "market share" in our vocabulary.
