It plugs on the right, I'm right handed, and the plug is on the right hand side of my office. Being an audio guy - bending wires/cables isn't a good thing and the way I have to plug it in, I envision that bending the power plug might not be good for it. Plus - the USB dongle for the wireless mouse can't plug into that side (at least comfortably). Yes, I know I can plug it into the other side (which I do). However - this is a minor hurdle that was overcome - it was just a tad annoying.
