13. HTC Nexus One
Key features: 3.7-inch AMOLED screen, 1 GHz Snapdragon processor, Froyo OS, 3G/wi-fi, and 5MP camera
Complex says: Google's first smartphone comes equipped with a speedy processor, enhanced voice capability, a stellar noise-cancellation system, and a stunning touchscreen that produces a 800x480 resolution. Along with contact and e-mail synchronization, it also gets the Google treatment incorporating trademark apps like Google Talk, Google Voice, and Google Goggles into the mix. An Android 2.2 update and niche features like speech-to-text give the Nexus One an edge over other devices.
