Finished it early Monday morning. It would have been sooner, but it was Mrs Wololey's birthday on Saturday and she insisted on being entertained and generally paid attention to (went to see the Wicked musical - very good if anyone's interested).
Book was very good, but she didn't half leave it open for further books if JK ever feel the need to further expand her bank balance.
As well as curses, I spotting a few unforgiveable cusses sneaking in there - did Ron not call Malfoy a bar-steward at one point?
