The SE was my question too—and I just bought a new one in Q4 after breaking my old one. Is it not the case that the average hand in China is smaller than the average hand in the US? I'm surprised they didn't mention this at all. Do they have data finding that reluctance to upgrade to a bigger phone was not a factor in reluctance to upgrade?

Does Apple report enough data for us to attempt to make correlations between average height (as a proxy for hand size) per country and purchasing decisions?
