Mario Queiroz - Vice President of Android Product Management

So what, exactly, killed off the Google phone store? We had a couple really good questions during this afternoon's Q&A regarding the death of the web distribution model, and what happened with the Sprint and Verizon versions of the Nexus One. Said Mario Queiroz, above, vice president of Android product management:

"The web store as a direct distribution model is really a very small part of the overall Android strategy. With the Nexus One we had the objective of bringing to market a very technologically sophisticated phone, which we did, which really set a new bar for quality. And I think you've seen a lot of the phones in the market today, that have come to market in the past few months, have been influcing, in many ways ... by what the Nexus One was able to do.

"The web store was another element of the strategy. It was, in many ways, an experiment for us. ... Android was in a very different place six months ago. ... And today, we believe that the right thing to do from a distribution perspective is different from what it was a few months ago. And so we've chosen to double down on our partnerships ... we're focusing on building great technology -- being an Internet software company -- and working with our partners on distribution."

Andy Rubin followed up with a great explanation with what goes into working with carriers. Check it out after the break.
