The second generation of the Google Phone, better known as the Nexus S, officially went on sale today in Best Buy stores across the United States. Is its presence in a major retail chain enough to avoid the sad fate of its predecessor, the Nexus One?

Last week, Google officially announced the Nexus S, a “pure” Google phone running Android 2.3, a.k.a. Gingerbread. In addition to a 1 GHz Cortex A8 processor, 16GB of flash memory and front- and rear-facing cameras, it also boasts a 4-inch Super AMOLED screen and design based on the Samsung Galaxy S.

Today, Google officially launched the device and reiterated its price and availability. Starting now, the Android phone will be sold in Best Buy and Best Buy Mobile stores online and in physical, U.S.-based stores. You can acquire one with a two-year T-Mobile service plan for $199 or buy one without contract for $529.99.

The Evolutionary Steps of the Nexus

---

The Nexus One was just as much a response to the power of the wireless carriers as it was a response to Apple’s iPhone. The phone was only available through an online store operated by Google rather than through retail stores.

The result of that experiment was utter failure. After lackluster sales, Google shut down the web store. The device never even made it to the Verizon network before it was killed.

Google has since realized that people like to hold their phones in their hands before buying them. Apple’s popular retail stores have been instrumental to the success of the iPhone, so Google has turned to Best Buy for distribution of the Nexus S

Still, the device is held back by its availability on T-Mobile only. AT&T and Verizon have larger networks and greater reach. And with the vast proliferation of high-end Android devices such as the HTC Evo and the Galaxy S, the Nexus S isn’t necessarily the must-have Android phone on the market.

Perhaps success for Google isn’t measured by pure sales but by the influence of its device on the market. The device will serve as a “clean” testing and development device for thousands of app programmers. It also sets a high bar for the quality of an Android device, thanks to its fast processor and the use of Gingerbread.

It’s not certain what Google is trying to accomplish with the Nexus S and future Nexus devices, but we’re certain it will fare better than its predecessor. While it will likely never reach the proliferation of the iPhone, it may prove to be a powerful weapon in Google’s war with Apple.

If you were hoping Google would help you save precious seconds in your search for “Sex and the City 2 torrent,” prepare to have your hopes dashed. The search giant is cracking down on piracy in a few ways, including blocking piracy-related terms from autocomplete.

Google () has blacklisted a few terms in its time, including “naughty words” and terms like “lesbian.” But this new measure goes beyond protecting children from hate speech and pornography.

Google General Counsel Kent Walker wrote today on the company blog that Google is instituting a new set of actions to help prevent copyright infringement.

In addition to providing more and better access to legally distributed content, such as YouTube () clips from a movie posted by the studio itself, Google is also taking some anti-piracy measures. The company says they’ll improve the process for DMCA takedown requests, beginning with Blogger () and Search content and eventually including all Google products. For responsible submitters, Google will act on requests within 24 hours. The company says they’re also trying to improve “counter-notice” procedures for people who believe their content was wrongfully removed from the web.

Google is also cracking down on sites that display copyright-infringing material while using AdSense.

Finally, the search company will start blocking certain terms in autocomplete. As walker wrote, “While it’s hard to know for sure when search terms are being used to find infringing content, we’ll do our best to prevent autocomplete from displaying the terms most frequently used for that purpose.”

That means that, like “lesbian,” “torrent” will soon be shifted to Google’s naughty list because more people use that term to search for illegal or inappropriate content than for legitimate, legal content.

The past couple years in particular have been a turbulent one for file-sharing and piracy. With Homeland Security seizing websites, the Pirate Bay getting slammed by a crippling lawsuit and even end users getting sued by the recording industry, voices like Richard Stallman’s are resonating more and more with the average Internet () user. To many of us, these anti-piracy actions seem like an ad hoc, punitive solution to a systemic problem: The recording and film industries are still learning how to come to terms with — and make money from — the Internet.
