Just registered to tell the OP thanks for the links. I hadn't even bothered to check Target's online inventory system; I knew all my local stores were out, and it sounded like they haven't gotten anything in since launch day. However, I came across this thread late last night and checked the 64GB Black Wifi Target links, and lo and behold - two stores in my area showed limited availability.
This morning when I got up, both still showed limited availability and another one had popped up as "Available," so I crossed my fingers and decided to make the 45-mile drive. I ended up getting there about 45 minutes after they opened and figured if they did have anything to begin with, they'd probably be picked clean already. But when I wandered back to Electronics, they had a case full of iPads and not a soul around (including any store employees).
When I finally got someone to come back and open the case for me, I asked how they had managed to have some in stock when every other Target, Walmart, Best Buy and Apple Store within a two-hour drive was completely sold out; he shrugged and said they must have come in last night, as they hadn't been there the last time he worked. Anyway, I walked out with the exact model I wanted; I debated picking up an extra to sell, but I decided I'd rather leave it so someone else could make a happy discovery at Target. 😉
Anyway, this is my long-winded way of saying thanks for giving me the push to check the online inventory; never know when you might get lucky!
