Micheal- in regards to lightening, I got popped a few months back. It was loud, bright.... and a complete non event other than the "whoa!!" that both of us exclaimed when it happened.
Not even a single message popped up on our system screens after the fact- the airplane took it like a champ!
I actually severely dislike being in the back- especially in coach away from a window. Nothing more disorienting than being shocked back into being awake after a nice jolt of turbulence. It's more about comfort and orientation for me. (btw, if you research turbulence, it is simply a small change in airspeed/direction in the airflow mass you are travelling in.)
