Just a little note. I went to watch a video on Vimeo this evening on my Macbook Pro. I started it up and literally watched the video drain from 100% to 64% in less than 30 minutes. I also noticed that it was awfully warm in my lap. That was about when I realized that I was watching the Flash version. I clicked the little button to toggle over to HTML5 and let me just say that the other 30 minutes finished using less than 7% more battery...and the whole computer is running much cooler. Can.
for flash to go away.
Another quick side note...played the same video on my iPad and it used less than 10% of the battery for the whole thing and barely warmed up.
