I just got mine today...not sure if anyone else experienced this ....when u graze the aluminium surface with your fingers while the power cord is attached, do you guys get any vibrating sensation? It dissappears when I unplug the power.

It's definitely not static shock...kindly tingly but with no 'bite'...best way I could describe it is being "bergetar".. If I lift it up, the vibration goes away. Seems to me like a grounding issue or perhaps a rather minute current is passed on thru the casing ..somehow? Being a lazy owner, I'm just hoping it would just auto-magically goes away in a few days.
btw..graze ermm...like 'touch+move' at the same time.

That's the first thing that crossed my mind I've tried switching to different wall sockets, with/without my UPS. I'll test it again at the office tomorrow.
I got mine frm my local dealer..I was tempted to get it frm Ajul but decided not to wait for my KL trip next week.. scepticism and the thought of lugging the box back on a plane home turned me off.
