I used to work for a retailer that was an authorized Apple reseller and the number one complaint about the old docks, aside from price of course, was that they didn't accommodate whatever third-party case everyone was using. This form factor looks like it was almost certainly designed to work with a number of third-party cases. In fact, this design is another item in a list of things that prove that Steve Jobs is indeed dead and not living in a secret compound somewhere. On the list so far - really long charging cable for the watch, larger iPhone screen, this dock...
I'm leaning toward the dock once I get my phone so can anyone offer an opinion on how their docks are working with non-Apple cases?
