I like the enforcement of the 'no phones/laptops/etc' in the seat back rules regardless of their original purpose. Since the proliferation of smart phones, it seems like every day someone ends up leaving theirs in a seat back pocket. Then it ends up being a crisis at the gate podium on a 20-minute turn for us to scramble to find and return it. Harder to forget your phone if it is not placed there in the first place.

That being said, having cleaned my share of cabins I will not put anything of my own in the seat back pocket. Rather disturbing what substances I've encountered down there. .
