I assumed wrong - as someone pointed out offline.  The web page I 
pointed you to indicates "Image Stabilization = No".

Reading between the lines in the description of Shake Reduction (SR), it 
appears it adjusts the shutter speed/effective ISO# to be faster when 
there's a whole lot a' shakin' goin' on.  In reviews of digital cameras 
I've seen in the past, high ISO settings yield poorer quality images - 
effectively grainier IIRC.

Having used a film camera with image stabilization (IS) (Canon SLR), IS 
can be a good thing, yielding about a half to a full stop extra exposure 
without motion blur in most situations.

SR is no doubt easier to do as it needs no extra moving parts, just a 
motion detector (accelerometer - ok, a wiggly part) and some software. 
IS (at least in my old Canon) required a motor driven optical widget in 
the lens, which sucked down the battery if used too much.
