I walked over to the nearby Barnes & Noble at lunch just to see whether anyone was lined up for Harry Potter and the Deathly Hallows yet. At 1:00 there were two people sitting in front of the door with camp chairs, one with a book and the other with a laptop, but that was all.
It was nowhere near the level of the iPhone launch last month, but then there are many more places you can buy Harry Potter, and there’s little risk of the book selling out.
