Thing is I can understand people not liking some things about the X.
But switching apps with a home-button better? WTF? Swiping the screen is way faster...
But it's much less precise, and you ca be prone to overswiping and bringing up a different menu, or not swiping enough and being forced to re-swipe or wait for the picker to show. Then, navigating to the exact app requires even more precision, on the same swipe. Moving around home button app icons requires similar levels of precision: try moving an app between screens and see if it places it where you want or expect the first time.
