well i only read half of the posts cos my computer is so slow, but here is my theory...
If Fawkes has the power to heal just by crying, surely he has the power to restore life by sacrificing his own. Didnt Harry see him fly into the flames at the funeral? If Dumbledore is such a great wizard, as good as Voldemort, surely he could have found some way of keeping himself alive... unless its JKR's way of proving the "i'm always with you if i'm in your heart" thing....
Harry was right about Snape all along. He has hated him all along, and no one listened to him. Every other time no one has listened to him he has been right!
Harry and Ginny will get back together, as will Ron and Hermione, and it will all be happy happy ending.
I reckon Malfoy comes good. I mean, seriously, its a kids book primarily, and JKR has to show that even "bad" people can come good if given the opportunity.
I loved the book. Much better than the last one where Harry was all cranky and hormonal the whole time.
