Had my first flight on a 787-10. Originally booked 1/2L but changed to 11D/G after reading comments here. 11DG certainly felt very private. Having just connected from a 773 sitting in a bulkhead window, the 787-10 seats felt incredibly tight, both in terms of narrowness and the closeness of the monitor and tray table. I found it uncomfortable to sleep. On the other hand my wife preferred the 787.
