gerbick, it kills the battery because a resistive screen is "passive" while a capacitive screen is "active." This means that there has to be more electricity pumped to the touch screen for it to be touchable.
But how much? I mean, all it has to do is notice that it's being utilized by two inputs and not one.

For what it's worth, I'm going by my kiosk background and it's not that much of a difference if any at all if you detect one or two (or multiple) inputs. You just have to code for that.
