It has been around for years! You have to be incredibly stupid to consider this something new and innovative.... The HP Touchpad and Palm phone line had these long before LG ripped it off... Also do note that in most cases, it takes longer to charge than just plugging in a micro usb cable...
LG did not "rip it off". LG manufactured it, Google designed it. The design language of the Orb and Android ICS 4.0+ and the more recent Nexus line in general are Duarte's work which..*surprise surprise* he used to work at Palm for as VP of Human Interface and User Experience (and he now works for Google as Director of Android User Experience).
