If you think about it, kids are exposed (hee hee) to a lot of non-phone cameras. At least they were, but I imagine they still are. Most of the sports teams my kids were on had team pictures and there are of course school pictures. Any kind of theme park has photographers stationed at various places to give parents the opportunity to pay for pictures of their progeny. Probably not many parents willing (yet) to shell out cash for a picture of their kid somebody took with a cell phone. Show up at any elementary school recital or play and you'll see gobs of actual cameras. I'm sure the kids notice. If they play sports into high school they'll see more than their share of multi-thousand dollar camera and lens combos.
