    Just received my 2016 MacBook Pro a few days back and I'm finally getting a chance to futz around with it.

    My girlfriend pointed out that if you take a finger and place it on the wrist rest area and move it across the surface the computer mildly vibrates, or perhaps it's a very mild electrical current. Does anyone else's do this? Should I be concerned?

    That is a super common thing with metal-cased electronics. I have forgotten the fancy name, but as I recall, it is not a result of "bad grounding", despite lots of people saying it probably is on the Internet. It's a weird electrical field effect, and should be completely harmless.

    My 13 inch does exactly the same thing but I'm not concerned because of what people have written here.

    My 15 inch has done this for years now. It is harmless, I asked Apple Support and they said that it is because of the laptop being built out of a metal casing. It is harmless, just a weird feeling.
