Reminds me of the Samsung Netbook PSU / Charger. Whilst it doesn't 
produce any QRM that I have noticed there was a debate on the user group 
about some users getting tingles from the exposed metal sockets etc.
Some felt it some didn't, one user said if you don't believe it try 
licking the silver trim round the edge of the case, err, no thanks.
On the scope I measured the often seen huge induced AC ripple from these 
dirty beasts.
