Yeah, flash is SERIOUSLY CPU heavy. In fact that's how apple justifies not using it on any of its mobile devices. On closer inspection, there's more than just two 'FLASH' bars on the iPad, I count at least 4.
If you want it to good THAT fast then turn flash off.
On the other hand, do you look at websites by pinging back and forth on them so fast you can't read the text ? Personally, I scroll slowly down, and only move quickly infrequently when I want to 'go to top' or 'go to bottom'. If you actually read websites, the video doesn't really show off a whole lot. Its not comparing like with like, and its not comparing a real life situation, so it doesn't matter.
