*minimized*, *background*, *not-playing* Flash Player (Safari Internet plug-in) eats CPU+battery #flashsucks. Amazingly, this "backgrounded" Flash Player process chewed thru battery on my MacBook Air 11" in less than 3 hours (I used "Activity Monitor" to see what processes were using CPU), while normally I get 5+ hours. The site was video.forbes.com running in Safari 5.0.2, and it was the only page open with Flash (I use ClickToFlash to make sure). Power-saving and laptop-speed-up tips: Install ClickToFlash.com to block Flash by default, and use the built-in MacOSX Utility "Activity Monitor" to find the "Flash Player (Safari Internet plug-in)" process and explicitly (Quit) it after you're done watching any Flash video etc.
