So I'm onboard the PHX-ORD flight right now. One (annoying) thing to note. The FA call buttons are on the IFE, and they're not incredibly obvious (they could be a button for a menu? or a ordering a beverage? etc.), so EVERYONE is pushing them, all the time. DIng. Ding. Ding. The crew has repeatedly told us about it over the loudspeaker, but it's not super successful. I feel bad for the FAs--every few minutes, the ding goes off.

One tiny design flaw. But it's definitely a thing. ::shrugs::
