Amidst all this HTML5-iPad hype, us Mac users are still stuck with Flash video for the vast majority of the web. My conundrum is that my MacBook Air completely slows down after about half an hour of a Flash video running even on 360p. I've found HTML5 to be significantly lighter on my CPU only utilizing about 30% when I watch video on it, as apposed to 140% with flash. My computer becomes literally unusable. The video becomes jittery, my mouse barely moves, any action takes minutes to perform. I have a revision B MacBook Air 1.86GHz/SSD with the 9400M graphics and Flash is completely hogging my computer's resources. Are there any procedures I can perform to rectify this issue? I'm running the latest Flash beta 10.1 beta 3 from Adobe's site.
