Re: Question on 3 captive buttons
The back button is where it always should've been, IMO! Seriously though, I can understand why others prefer it the Samsung way (easy reach for left thumb, used to Samsung phones, used to where it was on older models like the 4-button HTC's I had.)
I just think that back arrow on the left side is very intuitive and it was a quick adjustment for me.
BTW, I think that's a feature of the LG's -- custom buttons. So there's some useful things going on there with their skin.
