My only real complaint is the multiple sign-in, multiple payment account for media. It would have been far better if there was a consolidated login (ie. open ID -- google account), as well as a secure way to consolidate payment (eg. google checkout).

Of course, each provider would have to offer this feature, which makes it an unlikely wish in the short term!

I hope that Google considers including a payment API as part of Android, as it would be VERY useful for the design of apps that would like to integrate payment as part of their services without the perpetual requirement of sign-in/information/payment-credentials. Pushed through Google Checkout, and this could easily boost their revenues dramatically. It would be even better if the API was a stub that could allow for different payment services (and thus maintain its openness).
