It's this idea that really bothers me, I think. I don't know if the developer subscribes to this idea or not, but whenever I see an iOS app priced way differently to it's counterparts on other platforms I suspect it's either motivated by this idea or otherwise some principled stance against Apple.
In either case, it isn't nice as an individual to be singled out as a target for extra cash because of the platform you run on. Just because I use an iPhone doesn't mean I have more money than my peers (and in fact probably means I have less!). Even if that were true on aggregate, I still find it unpleasant, simply because there will be many exceptions.

Assuming the iPhone is yours, sure it does; at least, more money than a student who can't afford £17 for a learning tool. The iPhone itself is an asset that is worth money.
