As the saying goes, the iPhone 5 and 5S are both the best selling 4 inch phones you can get. If that is what you want.. It's like the Honda Accord or the Toyota Camry are probably the best selling cars in their class if that is what you want.
The thing is, not everyone wants to drive an accord or Camry. Many want SUVs or minivans. There is nothing wrong with that but it is what it is.
The wife has an iPhone 5 and I have a Lumia 1020. She loves her phone and I love mine. There are software features I wish WP8 had (alerts for missed calls, text, etc, notification center, control center.)and there are things that WP8 does that she wish iPhone did. (Live tile, AWESOME camera, info on the lock screen, etc..).. The arguing of my phone is better than yours is old. No one made me buy a Windows Phone and no one made me get my wife an iPhone. We bought them buy choice and if/when were are unhappy, both of us have the option to try the other OS or go to Android. JUST LIKE YOU!!!
I am glad that iOS and android are knocking on Billion apps. Sooner or later, that won't be selling point.. I can just hearing Tim Cook saying in a couple of years (We have 2 BILLION APPS, wooo peeee deee doo, I can't wait to try them all one day. RIGHT?). smartphone owners will never own/ regularly using anything close to a 100 of them. If I had to count how many apps I NEED on a phone, I think I would struggle after 15-20 and I am sure most would as well. Apps that help you make it through the day or week, not games that you play to kill a few mins.
Apple is even slowing killing apps in it's own store..... How many of you have downloaded or used another flashlight app since the control center in iOS now has one?...
