Google says goodbye to the Android menu button with Ice Cream Sandwich

With the introduction of Ice Cream Sandwich, almost no Android devices will soon rely on the Menu button that was removed in Android 3.0 Honeycomb.
Google has been trying to removed the menu button for a year now to make use experience easier.
The button is now replaced with navigation bar, the three dots on the right top corner or right bottom corner of the screen, depending on the app.

Like to see how serious Google is taking Android.
