I have been having a bit of a flick through the book again (can't quite face a propper second read yet). Two things struck me;
Why had Dumbledore suddenly been spured into action? I mean I know Voldemort had more or less declared open war on the magical community. But DD knew this was coming for years. Why had he only just started looking for or trying to confim the existance of the Horacuxes? I got the impression he had kept some of the memories he showed Harry for years - why hadn't he acted on them? My personal opinion is that he knew he was going to die and soon.
The other thing that I thought was so cool was that the Ministry of Magic can't really stop under-age magic. It is more by luck than judgement when they find someone breaking the law. Poor Harry was unlucky in as much as no other Wizards lived nearby so he stuck out like a sore thumb. This definately mopped up some of the loose ends from other books when Ron would say the twins had done magic on him and not been caught. Very clever
