Please be very cautious about these lowball deals on Nook tablets. The Nook brand is all-but on life support as rumors swirl that B&N will be taken private and either spin off or shutter the Nook brand. They are aggressively pricing the Nook hardware to prop up subscriber numbers, which after a couple of years of decent growth were flat to falling over the last year or so.
Keep in mind, also, that one possible suitor for Nook should B&N sell it is Microsoft, and heaven only knows that the Purple Flyin' Tile Interface folks would do to it should that arise.
Not saying you *shouldn't* pick up one of these Nooks, but keep in mind there's a reason they're being lowballed. Many of these Nooks have already been rooted with third-party ROMs available that turn them into a "regular" stock Android device.
There are several good, "straight Android" tablet devices out there, and the Nook reader software can be installed on just about any of them, so keep that in mind as you consider these B&N offerings. Just be cautious and informed.
