Here you have the first Nook stand at a Barnes & Noble in NYC. The $259 Double-screen Gadget That Stole All The Crappy Kindle Thunder will arrive in November 30. If you are in Manhattan, here are the addresses:
The Nook stand is located at the Barnes & Noble at 86th and Third Avenue.
Update 2: Another reader says there's another stand at the Barnes & Noble at Union Square. He says the units are not real, however: They are plastic mock-ups. [Twitpic via Twitter—Thanks Gabriel, Paolo, and Josh]
