I think that Google's service will eventually be better and more widely used than PayPal. Google will make the necessary changes to please its customers and I wouldn't be surprised if the features on Checkout supersede those of PayPal. This article seems a bit one-sided, and I think Checkout just needs time. People have a trust in Google for an unknown reason and Google plans to increase the trust of the consumer, and give PayPal a run for their money.
