I think it's maybe just a bit early? You need at least a beta chrome build for it to work nicely - so stable should be nice in a few weeks... You're right though it's a little extreme, but imagine the type of data visualizations we have in store in the next few years on the web. This is really cool IMO...
I experienced jaggy scrolling too. I realized that scrolling with the cursor keys or clicking to page down in the scroll bar looks that way, yet if you select and drag the scroll bar then it is smooth.
The end-result is a terrible experience for me. The scrolling is extremely jaggy even after the 3d-fluff has scrolled out of the viewport.
And the initial view with the skewed text is about as functional as those flash websites that were famous in the 90s...
