As a former Boy Scout in a troop that had a no electronics policy, I don't think a policy really matters.
Boys will find ways to distance themselves from the gorup if they really want to.
If you are going to ban boys from bringing iPods, to camping trips than ban novels as well.
If a Boy decides he needs some alone time it's probably for the best. I have always been a loner, I participated with and befriended most of the boys who were in my Troop. However, there are sometimes when you just want to have some time to yourself and listening to music is a great way to do that.
Now I do agree bringing Laptops, or iPads, and handheld gaming systems might not be the best option on hiking trips.
Just because of size and weight.
However, I did just purchase myself a BioLite CampStove, that recycles the fires heat as a source of energy to charge USB devices.
