Flew on Delta airlines recently.
You have a touchsreen on the headrest in front of you to watch movies and tv shows and play some games. Not a bad idea, but it also controls your overhead light.
I wanted the light on to read a book. To turn the light on I had to watch a 30 second ad before I was able to get to the screen where you control the light.
Let me repeat. I had to watch a commercial in order to turn the light on.
Epic fail.
