Has anyone else experienced this? Sometimes if I just run my finger/hand across the unibody, there's this weird pulsating feeling as if it has an electric current running through it. I never feel it if I just touch the unibody, only if I run my finger/hand across it. I first noticed it one time when I closed the lid on my RMBP but now I've been just running my finger across the palm rest area because it's so strange. Could it just be the texture on the casing causing a light skid with my skin, or some kind of defect with the coating? It's not a big deal to me, it's just interesting and strange. Anyone else experiencing this?
