Android dominate iOS by a huge margin, and I think it is ahead even in the high end segment. You can understand that people going for high end will spend more money on apps, but still price of apps is basically the same between iOS and Android, and iOS is not lacking in diversity including free software. So it is quite surprising that even a few buys from the middle and entry level consumers cannot offset Apple advantage.
And I write advantage, but I'm not even sure what it is exactly. iOS users spend more because they like Apple stuff was a nice narrative when Apple was a edgy high end alternative to mainstream. But in the smartphone world, Apple is mainstream, and yet the same behaviour is observed even with a much wider consumer base.
Is that because Apple brand is so strong that buying Apple change the consumer behaviour. (I have noticed that paying for stuff when you have Apple hardware is socially more acceptable. Like I bought BetterZip and my colleague didn't blink, but I paid for the Winrar license on windows and that was considered like sacrilegious. Like buying software for linux was considered weird but not on windows) Or is it because the Apple environment is just a tiny bit better that it makes a difference at the time of splashing 2 GBP on a game ?
Another alternative is that it is just that the app market is catching up more slowly than the hardware market, and it is just a question of time before sanity prevail. At least for the time being, my monkey brain is happy to have the social validation to have bought the "right brand of smartphone" :-)
