I think that everyone should exchange the phones. It would make things easier for everyone from flying on aircraft to re-selling their devices etc. There is just too much randomness with regards to which phones have the anode and cathode touching during charging or watching videos like the kid that got burned.
Small inconvenience to ensuring safe future use and ability to use the phone on a plane like all of the other kids
Besides playing the odds with this is just stupid and pointless when you can get a free exchange. Just a matter of delaying instant gratification.
