Wrong.  Since the evf is displaying an image from the sensor, which is optically stabilized, the image in the evf is stabilized.

Back before evf's, you were correct, as the view finder was a real view using mirrors in front of the sensor.

Wrong. The sensor is only stabilized at the moment of exposure, not during live view.

I was wondering about that, but some quick Googling suggested that it should be stabilized at all times.  Oh well.

Thinking to my experience though, there must be stabilization active once the camera is focused (half press).  When the camera is idle, there is little point to actively stabilizing.  But I believe that is true of lens stabilization too - the stabilization system sits idle but ready, and then activates when the shutter button is depressed half way.
