I flew UA 787-8 in Y r/t IAH-LHR a few months ago and found the flight to be very comfortable. I too enjoy the huge windows and it is definitely a quiet plane, from take-off to cruise speed very muted jet noise. The lavs have auto flush and auto faucets which are nice as well. Tons of bin space and the great led lighting are added bonus IMHO. I did notice I wasnt quite as dried out or stuffy headed and had less problems with my ears popping, always a good thing in my book.
