Hi, I just picked up a MBA to replace an aged white Macbook that I had since I am constantly carrying my laptop in a triangle of death between home, school, and work by foot in Boston and the MBA seriously fits the bill for my needs BUT.... I get a tingle when in contact with the computer and its not euphoria from having a new computer or because the air is so sexy or something. It seems mild but it is definitely irritatingly present and prickles seemingly at the points where hair touches skin especially up to my wrist. My hands then hurt after use in a creepy way. I tried showing a friend and he didn't notice it, but nor did I for at least an hour. This happens plugged in with the 3-prong/2-prong AND unplugged. I read about similar things happening in the past to peoples' Macbook Pro's and I personally went through 3 Vaio Sz's that had this issue but at least 3 times stronger/more painful due to the aluminum alloy palmrest and grounding issues. Have you had this experience? I'm considering trying to exchange at the apple store, but if this is just the way they are all made I guess I need to consider another computer?
