I understand and appreciate your argument, but I would like to point out that those limitations are no longer an issue. I find it more annoying to help someone in the Android world to so basic things like finding an app or changing settings, because the UI is so bizarrely inconsistent across versions of Android and models and makes. To give a recent example, a friend could not figure out to toggle WiFi on/off on his Lenovo, because when swiping the screen from above, only other things appear. One has to swipe twice, then the status bar grows and shows the WiFi symbol.
