The questions are already starting, thought I would start this thread along the lines of the other excellent seat resources on the forum.
Wiki has the info I have noted from videos, blogs and other sources, obviously all without having actually been on the aircraft yet myself so still subject to change once people get onboard and can verify, add or correct the info.

Please post your thoughts and questions in the thread...
Safe travels.
