Otterbox Blackberry Playbook Defender, Black (RBB2-PLYBK-20-E4OTR)
This product is the mother-ship surrounding and protecting it's special cargo! Though as many others have said, it does increase the weight. But to be perfectly honest, within an hour I realized that I liked the feel of the weight and design much better. The architecture of the hefty silicone backing has perfect hand grips, and I just feel so much more relaxed using my Tablet.
I have ZERO worries that short of being "run over" by a train (though I think it could withstand being "thrown off" the train), I have no concerns that my PlayBook could be in a situation that it would be damaged, NONE WHATSOEVER!
So I love the way it sits in my hands, it is wonderful to not have to wipe my touchscreen every half hour anymore and most importantly I am no longer playing with an undefended device.
(oh, my one little hang-up that happens "occasionally" is that some of the swipes and less so, taps, at times, they don't register and you have to click or swipe a couple of times. Truly though, it's not a huge issue)
