If you're in the US, the carriers offer the largest subsidy for iPhones. They offer the iPhone for $199 on contract and $649 off-contract, while other $199 phones are $549 off-contract. Even if you don't like iPhones, it makes more economic sense to get a $199 iPhone and sell it.
I don't know how you can mention old iPhones being obsolete with Android phones in the same breath. Most games still target iPhone 3GS since it is still the #3 most sold phone in the US (since its now offered free on contract). You have a lot more app-compatibility problems with say a Motorola Droid or Nexus One, which were phones released much later than the 3GS.
but if you're not in the US and/or are sane enough not to get completely ripped off by a contract (at least that's how contracts work in Europe) you have an iPhone which is from 600-800 euros. As opposed to that even the One X is just 599, never mind GSII at 500, Galaxy nexus at 450 or Xperia S at 420 (all of which are, at the very least on par with iPhone 4S if not better).
also on topic, setting a kickstarter for an indie iOS project is, I think, abusing the system.iOS projects aren't really as risky as PC or PSN/XBLA (never mind proper console titles) and will net the developer a lot of money, if reports on games making indie devs a fortune on iOS are to be believed.
Also refusal to port it to other touchscreen devices with market penetration (Android, maybe Vita) is not the best stance to take, in my opinion.
