Well, I was perusing Adobe's education site, as I am needing to order their CS 5.5 Design Premium suite. Their site is 100% flash coding (at least in the store). My MBA (with click to flash) started at 98 degrees Fahrenheit according to SMC fan control. After clicking to allow Flash on their site, sitting on the education store page for CS 5.5 for less than 30 seconds, my temps went to 160 degrees fahrenheit. another 30 seconds or so, I was at 199 degrees Fahrenheit and the fans were going NUTS! So, I closed Safari, and literally in 10 seconds or less, the temps went to 145 fahrenheit, and 30 seconds after shutting down Safari, temps are at 110. I am running the current beta Flash build. I know it's been covered here before, but it is astonishing the degree of negative performance from a mainstream plug-in.
