At the Google launch of its new “not-a-Windows-killer” Chrome browser, held at its Mountain View, Calif., HQ yesterday morning, Google Co-Founder Sergey Brin arrived late and looked casually dressed and very windblown.

But he was quite talkative about Google’s Chrome, the software to navigate the Internet that the search giant released yesterday.

Brin talked about a lot of aspects of its development and implications, as well as its business prospects for Google (GOOG).

(Google’s other Co-Founder Larry Page is also in a small part of the video, also talking about Chrome.)

In a follow-up interview with me on the same video, Brin talks about possible market share for Chrome, the Mac version and the reaction from the company-that-shall-not-be-named-much–Microsoft (MSFT).

(And, not to get too personal, but check out Brin’s luvvly-jubbly Cayman Red Crocs too.)

Here’s the video:

Also, here are links to three blog posts I did live from the launch yesterday, in order:

Liveblogging From the Google Chrome Launch: Hello, Sundar!

Liveblogging From the Google Chrome Launch: Toe Fungus and Pinocchio

Liveblogging From the Google Chrome Launch: Hello, Larry! (Wake Up, Sergey!)

Please see this disclosure related to me and Google.

Finally, Google Co-Founder Larry Page takes the microphone and thanks the Chrome browser team and compliments them for their efforts.

This is–as anyone on the receiving end of Page’s sometimes pointed manner knows (and BoomTown has been)–a big deal.

Page also starts to talk about how browser choice and innovation could make the planet a better place.

Of course! World peace through better browsing!

Then he moves on to questions from the media, bringing some of the Chrome team up to the stage.

There’s a sequence of very serious questions on how to move tabs, privacy, mobile issues, WebKit, bug testing, Incognito, distribution plans and ongoing support for Mozilla’s Firefox (yes, it will continue–plus, Mozilla HQ is across the street! Hmmm…).

Ooops–the other Google (GOOG) Co-Founder, Sergey Brin, suddenly arrives late. He slips into the lineup of “Inside the Actors Studio”-type chairs, looking like he just woke up, in what is a classic move by Microsoft’s Bill Gates that I like to call the “bed-head maneuver.” (I like the spanking red Crocs though!)

It’s a sleepy ruse, as it turns out, as Brin deftly deflects a question about whether Chrome is an operating system for the Web, given that Internet navigation software has become so integral to consumer behavior.

As in, a Windows killer!

Nope, says Brin (full video answer to come), totally ignoring my dubious look.

The distribution question is key, of course, since Google will want to get Chrome out there. So what’s the secret sauce? Because it is a “great product,” says Page.

As to why Google was doing this, VP Sundar Pichal said the search giant wanted to “start from scratch” in the browser game. Like baking a really good cake, one would assume.

When no reporter would get up and ask the obvious what-about-tweaking-Microsoft question, I finally did and also asked about the business plan for Chrome–as in, how will it help Google make more money?

Both Brin and Page answer again that it’s all about providing choice and also keeping the Web open, which will spur usage, which will rain more magical moolah down on the Googleplex.

Also (and video to come on this too), Brin later adds, Google never thinks of Microsoft (MSFT).

Well, at least on that issue it seems we’re back to Pinocchio–the long-nosed version–again.

Soon to come: BoomTown’s Chrome Launch video and one of just the sleepy-as-a-fox Brin on Chrome!

Until then, here’s the exclusive review in his Personal Technology column of the new Google Chrome browser by AllThingsD.com’s Walt Mossberg, which was published at the same time as the news of its product launch was announced by the search behemoth this morning.

Walt’s reaction is mixed:

“My verdict: Chrome is a smart, innovative browser that, in many common scenarios, will make using the Web faster, easier and less frustrating. But this first version–which is just a beta, or test, release–is rough around the edges and lacks some common browser features Google plans to add later.”

Anyone can now download Chrome, but Walt has been testing it for a week. He also reviews Microsoft’s newest version of its powerful Internet Explorer, called IE8, which he likes better than Chrome.

Money quote: “The second beta version of IE8 is the best edition of Internet Explorer in years. It is packed with new features of its own, some of which are similar to those in Chrome, and some of which, in my view, top Chrome’s features.”

A little tarnish on the Chrome, it seems.
