Completely agree. I'm so disappointed in Google for having Checkout for
years and not doing anything serious with it. I really wanted it to become a serious alternative to Paypal. But it's like they never even tried.
And it turned out to be huge mistake for them because they could've really used Checkout accounts from day one of Android, to get people to pay for Android apps. I still believe this has been one of the biggest obstacles on Android, because you need Google Wallet (which is brand new service, I guess) account to pay for apps, and obviously the vast majority of people didn't have one, and didn't bother to make one either, and they'd rather look for the free alternative of the app.
It's been getting a bit better since Android 4.0, since they are asking everyone to make an account at the set-up, but they are still behind, and it could've been much better early on if Checkout was popular.
