Long time user of both iOS devices and Nexus devices. The virtual control on Nexus is really handy and efficient. For example, multi-tasking switch, all you need to do is tab the virtual control and select app. On iOS devices, however, you need double press the home button and select app. The vertical alignment on Android actually show more apps at time than iOS with horizontal alignment. I understand fingerprinter reader, you could have it as it is and replace the home button with virtual one. And you will never deal with home button failure.
