United Airlines 777 Rear Facing Business Class Seats

I always wondered what the rear facing business class seats on United were like, so I grabbed one (with an upgrade) last month on a flight from Denver to Chicago to find out; I didn't want a longer test in case I didn't like the feeling. I really didn't notice a difference in flight.  The bigger issue with seat 9A was a missing window and claustrophobic feeling.  The forces experienced at take off and landing are reversed too; it wasn't uncomfortable, but just felt a little off.
