What confuses me is the decision to add an extra row to the Springboard. The obsessive in me liked that the iPhone 5+ and iPad could fit the same number of icons on a home screen. If the argument is more space = more icons, then they would have added some extra rows to the iPad a long time ago, or allow up to 6 icons per row like in the dock.
