How is the heat on your zCD?
I just threw a CD in the unit and left it playing in repeat mode for over an hour. The ambient temp in the room is ~67 degrees and when I felt the top of the unit, I would guess it was about 90 degrees. I say that because it felt neither hot nor cold, so it must match my skin temperature (on the back of my hand). Of course metal is pretty quick to feel hot or cold since it conducts heat so quickly.
