Contrary to what many others say, I am a huge fan of the new CX J long haul seats, especially in row 11 of the 773. As I travel solo most of the time, I really appreciate the privacy and happily disappear into the cocoon for hours. BA window seats are great for privacy too.
(For the same reason, I do not like AA F, because your head is completely unprotected by the aisle when sleeping; for me, row 4 would be intolerable because your head is right by the galley curtain.)

Small point, but I think the flight map system on IB is by far the best as you get to control the display, and can scroll the map all over the world at different zoom levels. I have not seen this on any other airline.
I found the CX flight map to be annoying as it constantly switches between different views with fancy rotating view-from-space images. Just because the technology makes it possible, doesn't mean it should be done.

Happy travels.
