I finally got my defender today and I must say, they've improved the design considerably over the years. This may be the best case Otterbox has ever put out. A quick once over reveals almost all of the problem spots in past cases appear to be addressed.
As for size, I don't know what it is about it but it really makes the phone look big. In reality its probably the slimmest defender I've ever had. Once you play with it for a few minutes the phone shrinks back to almost the same size it was before. It is actually really slim and form fitting. I'm completely satisfied.
Wife walks in...
Wife: Hey what are you doing?
me: Nada, phones finally rootable.
