I've had the dock for 2.5 months now, and I'm starting to see some problems. When I open it up, the mouse/keyboard don't register, and I have to undock and redock once or twice to get it to work. Once I do, it seems to work without dropping out -- unless I'm in a car. Using the dock in a car used to work, no problem.
At some point I'm going to try shimming the area inside the dock a bit like I've seen folks do -- will report back.
