Google Checkout Case Studies

[Sg4]

Have any of you seen case studies on Google Checkout that prove that using Google Checkout results in higher conversion/sales?

You'd think that the icon on AdWords campaigns would attract eyeballs, but does it result in higher conversions? I'd be interested in knowing. Thanks

I've seen posts elsewhere that say that it increases CTR (since people wonder what that button is... Google Checkout still doesn't have any name recognition for a large population), but not necessarily CR.
