Regarding the use of the lap-tops in flight, I have often wondered about the request before take-off not to use CD players during the flight (although I can't understand why not - perhaps someone can enlighten me?) but most lap-tops these days have CD drives in them.
Should we not use lap-tops with CD drives? or just make sure there is no access (by having no CD in them)? or should lap-tops with CD drives be kept switched off same as CD players?
