You can't say that you like Matt Smith's sonic, can you? That thing is hideous. It's like one of those grabber claws (with lights) from some boardwalk game.
I'm hoping some day to get a picture of Paul McGann holding that sonic and get his feelings on it vs. the Weta sonic he was given. The Weta looks to me like a slap together scrap sonic his incarnation would make while trapped in a dungeon or prison or abandoned satellite somewhere.
The more I think about it the more I don't want to see 8 regenerate into 9. That way 8 can stay eternal in my mind. Like was said earlier - thanks to the BF audios he really has become my favorite Doctor too.
