That feeling will disappear when you disconnect the mains adaptor, because the metalwork is no longer even vaguely connected to the mains supply. It will also disappear when your laptop is connected to any peripheral (such as a USB hard drive) that is itself earthed via its mains lead.

I doubt that taking it to the Apple shop will prove fruitful - my PC laptop does exactly the same thing, and as I said previously it's perfectly safe as long as your laptop's PSU is double-insulated (look for the square inside a square logo). In fact, some musicians dream of having 2-wire mains leads on their laptop PSUs, as this removes a major cause of ground loops!
