Interesting. Very Interesting.

Excerpt:

Advertisements on Google.com from companies that accept Google Checkout will display a small image of a shopping cart. Clicking on the ad will take customers to the advertiser’s Web site, as it does now. When customers decide to buy something, they will be offered the option to sign into Google Checkout and use the credit card and address information on file there. Customers that do not have accounts with Google will be encouraged to set them up.
