I find undesirable to buy a phone where a company can arbitrarily decide what I am and am not allowed to run on my device. Because economies of scale make things cheaper if many people want them and because I generally believe in fighting the power of arbitrary or harmful corporate decisions, I try to convince others of the importance of this "feature" (really it's more of a lack of an anti-feature).

Luckily you can still sideload apps on Android. The day they remove that feature is the day I take the time to figure out how to use an alternate OS.
