An accurate GPS receiver literally weighs a few grams now. I have one in my wristwatch. Weight and bulk aren't valid reasons to leave GPS out of cameras.
I don't disagree. For me, if I really cared about GPS, I would buy a GPS and drop it in a pocket. I would not tie a camera decision to its availability or unavailability because GPS does not really affect how I rate the quality of my photographs. On the other hand, if I was taking crime scene photographs where geolocation had evidentiary value, then my concerns might be different.
