Yesterday we brought you the first installment of our Nexus One video review series where we covered the unboxing, hardware design and compared it with an army of competing smartphones. Today in part 2 we cover the Nexus One's speed and take a variety of applications through their paces: new UI enhancements for Android OS 2.1, the web browser, YouTube, local MPEG4 video playback of high res and high bitrate video, Google Maps, the pervasive speech control and more. We also take a look at real 3D gaming-- something new for Android!
