Any illusions you might have about how HTML 5 can keep up with Flash 10.1 will be quickly shattered by this video. Never mind the narrator's thick French accent — as you can see in multiple examples, an animation achieves at least double the frame rate in Flash compared with playback of that same graphic in HTML 5.
Funny how Steve Jobs in his self-serving "open letter" propaganda didn't mention the astonishing performance deficit of HTML 5 compared with hardware-accelerated Flash.
Sure, there's lots of room for improvement in HTML 5. But Flash is here now. Just because it crashes Macs and isn't available on the iPod/iPhone/iPod doesn't make it undesirable for the rest of the world outside Apple's reality distortion field.
