Customer stupidity has risen a great deal in the last 5 years as well.
I don't care how many people want to use their phones to stream to their system, it is a bad idea. Tablets are cheap and can be secured in an area if need be. Dedicated controls are still a preferred option, especially when there are kids in the house that like to wonder off with the tablets (even the dedicated ones) - although I think a belt could fix the latter.
