As a developer I can not support the closed ecosystem that is iOS.

As a developer:
1. You need Apple's blessing to publish an application. There is no other way to get an app out there unless master Apple gives it their blessing.
2. You can't compete with Apple's native applications. If you have a fantastic new mail application tough sh#t, it won't be published.
3. If Apple decides to make the features of your app part of a native application you're getting the boot and tough sh#t

As a consumer:
1. You can not choose a new default application to handle various actions. Don't want Apple maps? Tough sh#t, when you click a map link that's what you're getting. Don't want built-in mail? Tough crap.
2. You have no choice but to use that bloated, awful iTunes application.
3. You can't view the entire file system on your iOS device (you can with Android)
4. You want an iPhone in phablet size? Tough. You want a water-proof smart phone? Tough. You can have this year's model or last year's model.
5. You get to overpay for that Apple logo; hope you like it.


The iOS app store is bad for developers and ultimately bad for consumers. Choice ultimately trumps; witness Android eating iOS's lunch.

I have never owned an Apple device and my house remains gloriously iOS free.
