If you want to pick up a new app on an Android-based smartphone, you have one option with which to pay for your new purchase: Google Checkout. At least, for now—sources indicate that Google is chatting with eBay’s PayPal business to bring the latter as a secondary option for smartphone-based payments.
Google Checkout just can’t compete with Paypal based on the financial model Google Checkout uses. Direct charge to a credit card versus using a virtual Paypal balance float is never going to work. Google’s idea was mostly well formed, but I think its time to give it up and go with Paypal.
