Sorry, the Nexus One phone is not available in your country.

Yes, the phone is getting a lot of buzz these days, but it may be the store where it’s sold that is the most important news for the future.

Gadjo is right that the other phone makers and carriers are in Google’s crosshairs – so, too, I think, are major online retailers like Amazon.

Google and its partners now have a dynamic direct-to-consumer channel, and we can expect not just Android apps and Nexus accessories to be sold. Other hardware, media content, software services and much more will be online.

But most of all, the Nexus One and its storefront will further Google’s advertising efforts.

Despite the phone, despite the store, Google’s main business is still advertising. So how will that be supported, expanded, empowered by an online store and mobile device?

Surely, online ads will appear in the store and on the phone.

Revenue will not be solely through retail sales, but through the sale of eyeballs, as well. Eyeballs on the go, eyeballs that can be geotagged to sponsor’s messages and entreaties.

As Mario Queiroz, Google’s VP of Product Management, says on his blog, “The goal of this new consumer channel is to provide an efficient way to connect Google’s online users with selected Android devices. We also want to make the overall user experience simple: a simple purchasing process, simple service plans from operators, simple and worry-free delivery and start-up.

“The first phone we’ll be selling through this new web store is the Nexus One … the first in what we expect to be a series of products which we will bring to market with our operator and hardware partners and sell through our online store.”

Whenever the doors open in the Great White North, we’ll see.
