I would buy a defender series if they made one. I use the slide out occasionally but I could get by with out it.
No defender series = naked droid for me. There are no other cases I like.
so far, the 2-piece design would be a better way to go ... simply because if you did need the keyboard, you'd have to take the case off to use it. i like seidio's innocase, so far it's been nice. i just don't like how there's no soft silicon membrane, so it's only there to defend against scratches.
guess that's the point of most cases/shells anyway ...
back on topic, i can see the otterbox has rubber covers on the buttons, is that part of a silicon jacket or are they just inserts ?
if it's indeed a silicon inner jacket, then i am sold on this ...
