The wild ride of Nexus One rumors continues into Monday morning with the first detailed images of the Nexus One making their debut at Engadget. The images reveal a rounded handset with touch-sensitive controls on the front, a trackball, a large capacitive touchscreen display, Bluetooth, and WiFi. On the back is a 5MP camera with flash and a large QR code obscured by a sticky note. The sides are equally as simple with a low-profile volume rocker visible on the left. The images also show off some of the new features of Android 2.1 including a new curved launcher wheel, extended homescreens, and a grid button on the homescreen which functions as a navigational aide by providing a preview of all open windows. DROID owners will notice the familiar lock screen and Power Control widget that is found in Android 2.0.1. Notably absent from the phone is both SenseUI and the HTC logo, adding further credence to the rumor that this phone may be released as the Google phone and not with HTC branding. More drool-worthy images after the jump.
