When I was in my local Apple Store here in LA, I was confused that they didn't have any Apple Mini DisplayPort to HDMI adapters on the shelves at all.

Then I saw they had these instead. The Apple Store had the Moshi adapters completely take the place of the old Apple MDP/HDMI adapters.

That must be the ultimate coup for an accessory manufacturer: having the manufacturer drop their accessory for yours in their own stores!
