i dunno about that, it is almost as easy as slide to unlike (same motion infact)... except you dont have to worry about typing your PIN/draw pattern or pocket dials plus you get security...it could be great for those bad behaviours such as keep checking your phone without having to insert the pin all the time...This kind of feature was a bit of a gimmick in higher-end consumer notebooks from 2006~2009 before it faded away. I imagine it will also fade away from the phone market in due time.
That's not the point, they said Apple "popularized"Motorola Atrix did this like 4 years ago and worked better because the reader was on the back top so it was easy to hold and slide finger. Talk about non innovated or exciting.
