I got ahold of a BlackBerry 10 Dev Alpha device and started to play around with it. I realized I didn’t need to open and close apps because of the way you use Active Frames. In much the same way you multitask with frames on your BlackBerry PlayBook tablet – keeping one frame in front of you while other frames are minimized – you can keep your most-used apps readily available.
If you think about it, the real world pretty much works the same way. Picture yourself preparing to take a walk: You put on your shoes and coat, grab your keys, and go out the door. The point is that you’re always moving forward in a general ritualistic “flow” toward the goal of taking a walk. You don’t put on your shoes then take them off to put your socks on.
If you are apprehensive about the lack of the U-turn back button or a traditional “home” hardware home button, don’t be. If you really get stuck, also remember that you can comment here or contact BlackBerry Support for assistance.
