I just started using a program called, "minitube". Here is the the developer's webpage, http://flavio.tordini.org/minitube. It is essentially a desktop program for watching YouTube videos. I don't know how Flavio does it, but I can watch YouTube videos without Flash. Since Flash was what made my MBA so hot and irritating, minitube made my MBA so cool. Yesterday I was able to watch 2 hours of Youtube without hearing fan noise. Temp remained in 120-130F range. I highly recommend it.
