That was the whole point of the keynote today. Google is trying to lure developers by being free and open. Apple is try to lure developers with cold, hard cash that they are paying out.

The keynote mentioned that Apple has paid out $1 billion to developers through the App Store and advertisers have committed to $60 million dollars so far to iAds. Developers get 60% of this.

I see or hear no numbers from Google. Google hasn't even rolled out Google Checkout worldwide, yet. The Android devices that Google is selling are being given away by the carriers. A customer that received a free device and has not input their credit card into a payment processor is probably not the type of customer that I want.
