As far as i'm concern, 4160B is rip off!
I can't find the post, but the picture with the specs of 4162B(at the time) was dated July 23rd.
And LG had no shame releasing 4160B in august who is a mild upgrade from 4120B.
A new drive should mean new hardware, and there is no difference between 4120B and 4160B.
I'm tired of seeing companys like LG and LiteON releasing new drives for every new generation of a more mature firmware.
I'm the happy owner of a 4120B. But when i will retired the drive for a new one, i will look elsewhere than LG for replacement.
Those who bought 4160B, should ask for a huge discount, or a free upgrade for 4163B. 4160B is useless!
My two cents!
