Apart from EMC issues involving laptops, games etc there is also the ROHS (lead free) issue to be considered. Airbus is a bit vague about how far they have gone with it but do have the usual green waffle about making progress in that direction.
For those who are not familiar with the ROHS problem basically solder joints are a lot less reliable than they used to be both initially and with cracking over time with vibration. There are also problems with tin whiskers growing and shorting between joints/tracks etc this can lead to them being zapped and disappearing leaving no trace just a one off fault.
