Sod the TV; 36" please! Ah but it's so difficult to please everyone. As for me, I would like to go back to the good old days of:
-A comfortable seat
-Adequate seat pitch
-a reasonable meal (depending on flt time)
-Friendly cabin crew
-all of the above for a fair fare!
I don't particularly care for individual TVs etc. I still prefer to read a newspaper or two and then get stuck into a good book. Most of the inflight movies are crap or not shown on the sector I'm on!
