Android was developed with one simple idea: Open up mobile devices to enable greater innovation that will benefit users everywhere. Nexus One, new Android mobile phone from Google. Nexus One is an exemplar of what’s possible on mobile devices through Android – when cool apps meet a fast, bright and connected computer that fits in your pocket.

The Nexus One belongs in the emerging class of devices which we call “superphones.” It’s 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.

Manufactured by HTC, the Nexus One features dynamic noise suppression from Audience, Inc., a large 3.7″ OLED display for deep contrast and brilliant colors and a 1GHz Qualcomm Snapdragon chipset for blazing speeds. Running on Android 2.1, the newest version of Eclair, the software includes innovations like a voice-enabled keyboard so you can speak into any text field, fun Live Wallpapers, a 3D photo gallery for richer media experiences and lots more. Of course, it also comes with a host of popular Google applications, including Gmail, Google Voice and Google Maps Navigation.

You can purchase a phone with service from T-Mobile USA. Verizon Wireless in the U.S. and Vodafone in Europe have also signed on to this program.

Price is $529 unlocked or $179 with T-Mobile USA service. This “coming spring,” the Nexus One will come to Verizon. You will need a Google Checkout account to buy the phone. On the site, you can enter two lines of laser engraving and you see a live preview of what the engraving will look like.
