Re: SMS messages on Android
Well the iPhone owners probably have not had to deal with Apple foisting a completely different app (from an SMS app to Hangouts) with a completely different UI to manage texts.
This is on top of changing the calendar app enough that it's impossible to tell which month you're scrolling through when you're trying to tell someone "yes, I'm available mid-July"
Then there's the disappearing functionality from Maps, like zoom buttons.
I've used Android since the Droid/Milestone, hate Apple, but I am SERIOUSLY considering an iPhone now.
