>Yeah people just turn it off and then can just scan a page instead of talking it . Much faster.

No, that does not work. They think they can, but there is no study that shows that information retention is high while "scanning" a page. That is one of those myths like subliminal messaging and other semi-esoteric bullshit that seems to make sense when you first hear about it. It is utter bullshit and. does. not. work.
