They've moved the "display in stores" date from Nov. 30th to December 7th. If you look on the B&N help board there is alot of discussion on what, if any stores, will have units to sell.
Hopefully next week some people will start to get nooks into their hands and we'll start seeing some real reviews of the unit. Right now they haven't even supplied the tech mags with real operational nooks - just the literature and videos.
