My Technocel cover and holster arrived the other day, but I've been too busy to take/post pics until now. First, the cover fits like a glove, and snaps together easily, leaving no wiggle room once installed. The holster is reminiscent of the OG Droid holster sold by Verizon, but this one is designed for use only with the cover. The ratcheting mechanism on the belt clip is weak, allowing the phone to spin too freely. While this is a far cry from the belt clip on the shell/holster sold by Verizon for the Bionic, it's no worse than the belt clip on the previously mentioned OG Droid holster. My only other complaint is that the spring clip sticks out farther than I would like, but this seems necessary to allow the phone to push the clip out of the way when you're placing it in the holster.
But does it fit in the docks? Standard dock - yes, easily. Car/vehicle navigation dock - physically, yes; dock detection, no. But there's good news - at least for those willing to take a dremel or file to their dock. The problem with the car dock is that the phone with the cover installed sits too high in the dock for the USB connector on the dock to insert all the way into the phone - otherwise the phone fits fine, and the retaining latch easily reaches over the phone without having to force the phone into position.
I was able to remedy the problem with the USB connector by removing the back from the dock, removing the USB connector, enlarging the opening that the connector comes through (using a file), and slide the connector up about 3/16", epoxy the connector in place, and re-assemble the dock.
Here are some pictures of the cover, holster, and dock (pre and post surgery), as well as the installed dock, using the i.Trek IG-PSTARA sticky dash mount (small adhesive rectangle with post & ball).
