'm not affected by wifi or cellphones, but when I place my MacBook Pro on my lap and wait about 30 seconds I can begin to feel tingling deep inside my legs, like in the bone.
I have felt the same thing and since I have been electrocuted and know what that feels like I was able to figure it out pretty quick. Check to see if the circuit you have it plugged into is actually grounded. I have a similar issue with my work laptop when I am in Europe and have to use an adapter so my laptop isn't grounded. I have also had a similar experience in some hotels in the US where the socket isn't grounded as well.
I don't know how much they pay for the in-flight entertainment now, but I bet Netflix could undercut them (especially if they provided a limited catalogue to everyone and a less limited catalogue to their customers. One interesting option would be for Netflix customers to indicate their flight number and select things to be cached before boarding, while the plane is at the gate).
That would be too awesome of an idea and since the airlines seem to be in a never ending death spiral of passenger discomfort it will never be implemented. It wouldn't surprise to to find out that airlines are actually paid to show some of the crap they have.
