Among the biggest surprises was the addition of a physical "home" button like the one found on Apple's iPads and iPhones. This replaces the "soft" home key of other models and works anywhere, any time to bring the focus back to the home screen. Like the old home key, a long press brings up a list of running apps to tap into action or sweep away and kill. So what used to be four soft keys -- back, menu, search and home -- has been replaced by soft keys for menu and back functions straddling the physical home key. Controls for power and volume are still identically located on the right and left sides, respectively.
