- Soft vs Hard "Home" Button: I do miss having a physical button on the front of the phone; the iPhone's home button is perfect for waking it when it's resting on a table. However, the soft home button is a much smoother experience once the phone is on - not having to apply any pressure feels lighter, nimbler, and just plain better when navigating. Winner: Tie.
- Menu & Back Buttons: Android has the edge here. Those two extra buttons come in very handy, and are conveniently located in an area that's otherwise unused. It beats double-/triple-tapping the iPhone's home button; Apple claims that fewer buttons simplify interactions, but that's just wrong when you start depending on multiple taps and long holds. Winner: Android.
- Standby Buttons: I thought I'd miss the top-mounted standby button on the iPhone, but it turns out that was just a learned habit that can be re-learned - now the side-mounted power button on the Nexus feels just as natural. Winner: Tie.
