I'd love to see how fast my Android phone runs with 2.2. Too bad I can't. One thing the iOS releases have going for them is that users can actually get them when they are released. 48 Days later, I still don't have the 2.2 update.

"Today is one of those days that has my heart racing; we’ve just released the source code for Android 2.2."

Regardless, your statement seems to contradict itself. If you can't install 2.2 on your phone, then it isn't really "released," is it?
