The AA J seats on the 777 are the same as on the 767-300 and as Dave points out the pitch is 60 inches (compare with QF Dreamtime at 50 inches). So there is plenty of room to get out from the window seat to the aisle even with the aisle passenger fully reclined and sleeping.
These seats are very comfortable for sitting and recline further than QF Dreamtime seats. But if you want 180 degrees of recline you have to find a way of getting into the F cabin.
The IFE is a multi-channel loop system similar to QF's non-AVOD, with the screen swinging up from the front of the arm rest.
All J seats have in-seat power provided by car cigarette lighter style plugs, which work with the Targus travel power adapters for most laptop computers.
Remember to select your seat based on FEBO, which is where the meal order is taken from the Front on Even flight numbers, and from the Back on Odd numbered flights. On long flights where there are multiple meal services, the first is FEBO and the second is the reverse. And they will run out of at least one meal choice by the time they get to the passengers who did not observe FEBO when reserving seats.
