Ice Cream Sandwich – Folders and Gestures
On the design side, there's a new typeface called Roboto that has a clean, modern feel, as well as UI tweaks imported from, ahem, other mobile operating systems. iOS 'donates' folders, instant photo uploads to the cloud (via Google+, natch) and an Action Bar that replaces the old physical navigation buttons. Palm's WebOS hands over its nice flick-to-dismiss gesture that you can use throughout Android 4.0, for example to get rid of apps in the multi-task button, itself lifted from the tablet-only Honeycomb.
