The latest publicly available Android iteration brings Google Now On Tap which scans the content on your screen and is capable of pulling out relevant information about it, Doze Mode which improves the
battery life of your smartphone while idle by putting apps in a deep sleep state, a new app permissions system which enables apps to ask for permissions only when they need to access certain features of your phone, Chrome custom tabs for faster webpage loading
within apps, automatic app data
backup, Direct Share for faster and smarter sharing with the people you contact most often, Deep Linking so you won't see the app selector that often, and more.
Obviously, you also need to be
within reach of a power socket; I'd have liked to have seen a
battery onboard for at least temporary
backup purposes during a power outage.
