During today's BlackBerry World keynote, Thorsten had Vivek Bhardwaj show off a bit of the flow that BlackBerry 10 will have. During his demonstration he showed off application switching and multitasking. The sliding screens look amazing! As he says at the beginning of the clip above "It's not just about being notified about a conversation. It's really being immersed into it instantly." He really shows how BlackBerry 10 will have that one handed operating ability that Kevin talks about.
