Take a closer look at BlackBerry's new Z10 phone and built-from-scratch BB10 operating system.
BlackBerry is very proud of its new Flow multitasking interface, which eschews all button pushing not related to volume or sleep in favor of gestures. While it's not all that different from pressing a home button, swiping up to exit an app and having the tiles of every other open app immediately appear in front of you is a wonderful touch.
