I acutally wasn't surprised that this was possible, but now someone has really demonstrated it.

Interesting. Wireless keyboards are even more dangerous, though.

It mentions "cost pressures in the design". Would it be possible that older, more expensive keyboards emanate less electromagnetic energy?

I guess that electrotatic insulation in cheaper models leaks more electromagnetic pulses. My mouse's cord is so thin that I belive there aren't any electrotatic insulation besides the rubber insulation.
