iPhone, iPad Users - Do not uprgade to iOS7!
I saw the user interface for iOS7 on a friends iPhone and it is crap - all eye candy that is actually slower to use than the previous system and harder to read. It is also more computing power intensive so it needs an iPhone 5 to run fast. This is not a pilot friendly operating system.
Basically Apple have decided to animate every function and icon on the phone to make it "cool". However coolness is a relevant to a tool like a phone as it is to a wood saw.
If Apple continues down the "coolness" road then they will become irrelevant very fast.
Message to Shagpile: I hope there is an Android version of Ozrunways coming, because Apple is going down the same "coolness" road that destroyed the Motorola flip phone as a professionals tool.
