what exactly is BSE? it's being compared to ishield/zagg and bodyguardz. i'm having trouble deciding since i've been using zagg. but i've heard that bodyguardz gives the product a more natural/ naked feel. i wouldnt know because i've never used it but i know for a fact that ishield/zagg slightly interferes w/ the sensitivity of my touchpad on my macbook and the click wheel on my ipod. i'd like to hear the opinions of those who've used both (ishield/zagg and bodyguardz) and know what exactly theyre comparing. and even possibly bse, whatever that is.
