AC is really like the old wife who .....es you around but has become part of our comfort zone. Not the greatest on earth, sure. But at the end of the day, still the most convenient for most of us, especially with varying flying patterns. Coming back home and walking into an AC plane makes you feel home right away, with warts and all.
Additionally it's such a wonderful target to get at. Especially about IT... Aren't we having fun?
