&#62; Consider that in general games and rich interactive things take more CPU than static HTML and graphics, so of course it will take more CPU to render those things. If you don't like it, don't play Flash games and boycott sites that use excessive poorly coded Flash.<p>There are Javascript/CSS demos out there that are <i>much</i> more dynamic/interactive than the average Flash based ad that still use less CPU.<p>In a similar vein, there are other Safari plugins out there that do much more than the average Flash based ad that use less CPU.<p>The Flash plugin uses more resources than people expect it to based on their experience with Flash in Windows, as well as their experience with other technologies on Safari/OS X. I don't think it is a collective hallucination.<p>Flash on OS X could be better.
