B&N is discontinuing the Nook and Nook HD, which is unfortunate. Still, they're good tablets and ePub is still a common format, so if they start unloading these things cheap I can't think of a good reason not to get one.
B&N is still in their partnership with Microsoft. Win 8 ereader/tablet coming?
