OK, here's my random story. I bought a 'Genuine' Powerbrick of eBay for my 12" Powerbook. Turns out its an amazing fake (ie, the only way I could tell was the cheap plastic nubbin on the cable and the fact that the sticky plastic cover left residue all over it ). I really don't mind its fake as its a bloody good fake. Randomly though, sometimes when i put my fingers over the wrist rest area, i can feel a very mild current going through me. At first I thought it was a vibration but then I touched my other half with my other hand and he felt it too. Its a little strange but I wanted to check I'm not in any danger Plus now if I run my fingertips over my new MBP's lid, it gives me the same sensation. Am I crazy?
