I've been using the Nexus One with Vodafone from past few days as my primary mobile phone. This is the best Android powered phone to date. It's also the fastest and most elegant smartphone on the market today, solidly beating the iPhone in most ways. In this rapidly evolving market there is sure to be something better just around the corner. But if you are looking to buy a high end smartphone right now, this is the phone for you. The Nexus One is the Android signature device.
