Sorry, Google, but PayPal still reigns

It has been a year since Google launched its much-anticipated payment service.
In many ways, I found Google Checkout much easier to use than industry leader PayPal. However, Checkout does not work with the tasks for which I've been using PayPal.
Checkout works well as an online wallet, a way to store credit-card numbers and addresses so you don't have to retype all that information each time. PayPal functions more like a bank account: You can do much more, such as receiving money, but the array of options can be confusing.
But Checkout isn't accepted where it counts. Google claims tens of thousands of merchants accept Checkout, compared with millions claimed by PayPal.
Unlike Checkout, PayPal sometimes lets you make one-time payments without creating an account.
With PayPal, you can receive money in about 50 countries, while Checkout accepts U.S. and United Kingdom merchants only.
Most importantly, Checkout won't let you receive money with regular accounts; you'd need a special merchant account and provide a Social Security number or federal tax identification number. I haven't used PayPal often to get money, but it sure came in handy when I've needed to.
