I like the dock, I haven't used one since the iPhone 2G but I can see it coming in handy on my nightstand. I may pick one up!
If it covers the bottom, then no unless it's a ridiculously thin case. It works with all Apple cases as the bottom is left open.I was looking to get the rose gold stand to match my rose gold iPhone when I get it however I am wondering can it be used with a case on the iPhone? I use a clear case that covers the bottom. don't really want to spend that much money if it can't
