"One of the most prominent new features on the Galaxy Nexus, and Ice Cream Sandwich, is that the soft-keys are displayed right on the screen. While the notion is a sound one, there will always be those who miss some of the legacy features left behind. In this case, those would be the Menu and Search keys, stalwarts of Android's interface paradigm since its release with the G1. What was once four buttons - Home, Menu, Back, Search* - has been whittled down to just Home and Back, along with the introduction of the new multitasking-purposed App Switcher button. This combination was seen previously in Android 3.0 Honeycomb, but is about to encounter widespread use on upcoming phones**.
