BlackBerry 10 is a fantastic feature, it might not be commercially successful, but it certainly better than Android and iOS in certain aspects. I don't have BlackBerry 10 devices yet, because I am waiting for that big 5 inch Q30. One of the feature I like is that the ease of unlock your phone. You no longer have to press the sleep/weak button, swipe to unlock. You just swipe up when device is sleep. I certainly fell this small thing that really enhance the user experiences. I really hope one day that iOS user not longer need to this 2 step process every time to unlock device, because we unlock our device quite frequently and it is hassle to go through this 2 step process over and over again.
