I am getting mild electric shocks by touching the case of the new MBP 15" while it is plugged to the power supply. I also found the culprit: It is the connector! Apple has decided not to include the cable extension, which has a ground. The small plug included with the new MBP has no ground, therefor I get small and mild electric shocks. Now I have to buy the electric cable extension, which were usually included in previous MBP.
