I have never been keen on these devices at the poker table. You are not allowed use your phone at the table so why are you allowed other electronic devices?
I played the 100k at DTD on Saturday and my table looked like PC world, at 1 point 7 of the 9 players had head phones in listing to rubbish, I say rubbish because every couple of minutes they start playing with their machines. If this was not slowing the game down enough 3 players also had i pad’s on the go.
I feel these machines should be covered by the same rule as phones. You want to use it leave the table. Turn your music on stick it your pocket and leave it alone. You are a grown up not a child playing with a new toy.
This would at least make players get their play list right.
