The Nexus One is a smartphone from Google, which uses the Android open source mobile operating system. The device is manufactured by Taiwan's HTC Corporation, and became available on January 5, 2010. Features of the phone include the ability to transcribe voice to text, noise canceling dual microphones, and voice directions while driving.
The phone comes unlocked and is not restricted to any particular mobile network provider. Google currently offers it for use on the T-Mobile network in the United States; a version for use on the Verizon (US) and Vodafone (European) networks is expected in the second calendar quarter of 2010. When it was released, reviewers found it to be the best smartphone that ships with the Android OS.
