I haven't read this entire thread BUT I do agree with the OP that I would rather my children not bring their GBoys because they can play them at home. But with that said, I do have a child with special needs---even though he doesn't play a GBoy my friend's child does. She mentioned how much this helped her son while he was waiting in line. He has autism and you don't know anything is wrong just by looking at him. It helps him prevent meltdowns by getting his attention focused on the little screen and forgetting the happenings around him. So just a reminder to all that sometimes we are quick to judge but there may be other reasons people are doing things. So if you see my kid eating his ice cream in a dish without a spoon or wearing his shoes on the wrong feet or any other strange thing---it may just be because he chooses to and we as parents choose not to make an issue so that we can just "get through our day". Thanks for letting me explain and vent a bit.
Adding to this post---since I didn't read but the first page of posts I'm now seeing that there has already been some posts on special needs kids. Didn't mean to add to the flaming that I am thinking may have happened. Guess I should have read the entire thread. Oooops. Anyway...my little 2 cents.
