Cognitive Style of Powerpoint

The author obviously has a very strong point - Power Point sucks. That said, he continues to barrage us with the point over and over and seems to blame the program itself for being poor. Obviously it is a mistake to use a program for a function which it is not fit - the Columbia example proved this beyond doubt. However if there is a fault with the system, the system is faulty, and if we continue to use a faulty system, then we are faulty. I don't think the finger was pointed strongly enough at the user - "YOU there, stop USING this crap" as opposed to "Don't you see how PowerPoint is going to ruin our lives if we don't kill it soon?"
