Assuming your HTC Flyer isn't stained black, then here's something to complement the Gingerbread tablet's pristine silver and white hardware.
It's the official microUSB desktop docking station that holds the Flyer in portrait mode and supports an MHL adapter via a rear port. It's also got what looks to be a large power button on the back that likely involves an LED ring that glows or blinks in different colors to indicate charging status.
The dock is currently backordered at Best Buy but will cost you $49.99 when it ships either directly to you or to your nearest store for pick-up. I assume the dock will eventually be available in black to match the HTC EVO View 4G (Sprint's version of the Flyer) but if you don't care about the color and just want the functionality, then have at it below.
