I felt this effect for the first time when I was living in Israel for a few months. I couldn't rest my wrists on my MBA while it was plugged in because of how painful it was. People said the power was "dirtier" over there than in the US (lots of voltage spikes? rougher waveform? not sure) so maybe that made it worse.

Assuming you're coming from North America, I found across Europe when my laptop was plugged into 240V I would get this, while 120V in North America was fine. It would also vary depending on the power draw - when the battery was recharging it would be worse (I think). I ended up unplugging and running off battery as much as possible, and eventually buying a smallish bluetooth keyboard and mouse to take on trips.
