Barnes & Noble is having a minor Sandy related distribution snafu, with many stores having limited supplies and some stores having none at all. Even B&N.com is so short that they won't be shipping any more orders for another week. This was truly unfortunate for me because I had been wanting to buy the HD+, and I hate waiting.
But today my wait was over. My local Target store in Woodbridge VA has both the 7" and the 9" models in stock. They also have some cases.
This is rather curious because the website said that my store only had the Nook HD+ on hand. Obviously the website was wrong, and I would not trust it to accurately describe the stock situation at any other Target store. You'll need to check in person.
But I have my 9" tablet in hand, and I'm looking forward to playing with it. I had little interest in trying yet another 7" tablet, but the differences inherent in a 9" screen size could be interesting.
