So far I like what I see with Android 4.0, it feel like a more polished user experience. it looks like Google has understood what mistakes it made with Android 3.0 and adapted it success from Android 2.3 to combine in creating this latest O.S upgrade. The truth here is Android 4.0 is and feels like a well fleshed out and polish version of Android 3.0. Which is a good thing here. One of the major keynotes here is battery life, which all Android devices struggle with. From the looks of things here, Android 4.0 has greatly improved the situation and has brought in better battery management and longer battery hours.
