Yes I jumped on the Harry Potter bandwagon too, I didn't go to the midnight release, but I was there at 7am when Wal-Mart opened (even though it compromised my principles a bit to do so). I even stopped reading a book I was half way through (Michael Flynn's Eifelheim) in order to get through this before I heard too many spoilers.
And man was I glad I went out of my way to read this thing, it is a great book. The series comes to an incredibly satisfying conclusion, with every character, hero and villain, given a chance to shine (in many cases right before they die). The book is a bloodbath, which I was not expecting at all, but only once in the book did it ever feel excessive to me. After 7 books Rowling has earned her apocalyptic battle between the forces of good and evil, and she does not disappoint her readers in its telling.
