In remarks at Microsoft’s Worldwide Partner Conference today, COO Kevin Turner said Microsoft has settled on a location for the retail stores it announced earlier this year: Within spitting distance of Apple stores. “We will have some retail stores that are opened up right next door to Apple stores this fall,” he said.

There goes the neighborhood, right? Anyway…

So Microsoft is going to play McDonald’s (MCD) to Apple’s Burger King (BKC). Makes sense. Apple’s retail locations are very well chosen. Microsoft, if it’s going to go this route, would be wise to have stores there as well. As economic theorists Charles ReVelle and Harold Hotelling once observed, “The best position for a new vendor is back-to-back with the well-positioned first vendor, allowing an even split of the market. Any other position of the new vendor would have given that new entrant a smaller market share.”

And one could argue that Redmond might benefit from a retail presence that brings all its wares together in a single “shopping experience”–Windows, Xbox, Zune. All that partner hardware. Surface. Put a Project Natal booth at the back of the store to draw foot traffic and who knows what might happen?

It is an extraordinary market play. And an unsettling one. For it seeks to place Google (GOOG), which already collects vast amounts of data about our Internet use, at the very center of our information experience.

The privacy implications are, of course, horrendous. And while Google will inevitably dismiss such concerns as paranoid and argue that any data the company might collect at the OS level will be used only to improve its services and benefit users, it should still give us all pause. Because when it is finally launched, Chrome OS will be yet one more deep well of consumer data to which Google will have access.

There are already quite a few such wells, including Google Search and Chrome, that profile user interests and surfing habits: Gmail, which gives the company access to our email conversations, and Google Voice, which gives the company access to our spoken ones. Add to this Google Street View and Latitude, a service that tracks the physical location of its users, and mobile and desktop operating systems and, well…that kind of consolidation of Internet-based services around a single dominant company should give us all pause.

Lest we forget, Google is in the behavioral targeting business. Why would people ever use an OS developed by a company whose business is based on meticulously recording and analyzing their online behavior? Because they enjoy using its other services, I suppose. But there is a privacy-vs-ease-of-use tradeoff here. And with Chrome OS, it is unprecedented. Further, while Google might tout its “don’t be evil” motto as reason enough to trust the company with our data, there are other entities that don’t always share that sensibility. Remember, it wasn’t so long ago that the federal government tried to force Google to turn over user search data to the Justice Department…

“Competition in the OS market should always be welcome, but Google is the special case,” Marc Rotenberg, executive director of the Electronic Privacy Information Center, told Digital Daily. “It has become dominant across many essential Internet services–search, mail, video, online apps, and advertising. Coupled with Google’s growing profiles of American consumers and reluctance to adopt meaningful privacy safeguards, we expect that antitrust authorities in the US and Europe will view Google’s entry into the OS market with enormous skepticism.”

Jeff Chester, executive director of The Center for Digital Democracy, echoed Rotenberg’s concerns. “Google’s new OS has to be placed under the data collection X-Ray by US and EU privacy regulators and advocates,” he said. “Any expansion into the marketplace by either Google or Microsoft should generate intense scrutiny, especially for the privacy implications. These two are engaged in a global data collections digital arms race, which has far-reaching implications for consumers and their information.”

“Today we’re releasing a new feature to find your local news by simply typing in a city name or zip code,” Google software engineers Andre Rohe and Rohit Ananthakrishna wrote in a post to the official company blog. “While we’re not the first news site to aggregate local news, we’re doing it a bit differently–we’re able to create a local section for any city, state or country in the world and include thousands of sources. We’re not simply looking at the byline or the source, but instead we analyze every word in every story to understand what location the news is about and where the source is located.”

Location-based news targeting. Pretty slick. Or it will be, once they get the 90210 bug worked out. Still, as Topix co-founder Rich Skrenta notes, Google’s a little late to this particular game. “This was pretty neat stuff when Topix launched in January 2004,” Skrenta quips. “Now if Google just added 50,000 vetted local blogs to the mix, and a community with 100K posts/day, they’ll have something.”
