Amazon CDNs

I know just enough to be …”half-dangerous”! So feel free to contribute to the community and my ‘limited’ knowledge.

As I understand it, most of the popular CDN’s just speed up the static parts of our WordPress site(s), correct?

So now, according to this article, Amazon’s going to speed up a lot of the php requests as well, right?

Doesn’t this new feature pretty much leave the other CDN’s in the dust?
