In the U.K. they come with earthed plug. However I still noticed "buzzing" in the MBP, MBA and even iPad when I would touched them. Took the MBP in to the store. It didn't buzz there. They gave me a new power supply anyways and recommended I connect the plug directly into the wall socket. Turned out that the power strip I was using is not grounded even though it has three pin sockets ! When I plug Apple devices directly into the wall socket I don't notice any "buzzing". So now I don't connect the Apple devices via a power strip.

Throw away that power strip.

  As in, right now. It violates every electric safety law around.

  I would rather at least try to disassemble it before throwing away - otherwise it is likely that someone will pull it from the bin and use it or sell it.

My UK MacBook came with two plugs; one with a long cable and an earth connection, and one "short" one that's just the plug head, with no earth connection (the slot that the earth ring from the transformer connects to is just plastic inside). I get the shocks when using the short connector, and always have. Here is a DIY guide by someone who figured out how to fix the issue (danger, electricity, don't kill yourself) http://garethhayes.net/apple-power-plug-not-earthed/ http://garethhayes.net/apple-power-plug-not-earthed/
