While there are already many phones from other brands on the market using Google's Android operating system, the Nexus One is the first phone to be sold by Google itself - although it's actually manufactured by HTC. There aren't many differences between the Nexus One and what's already available, such as Motorola's Droid, or the HTC Hero, but Google has introduced some of the latest and greatest technology out there. The Nexus One is one of the first phones to feature a blazing fast 1GHz processor from Qualcomm, which should provide more than enough computer power for the phone's various applications, including multimedia and 3D graphics. Another impressive feature is the display - a 3.7-inch Amoled capacitive touchscreen, which has received rave reviews from anyone who has seen one. It also has 480 x 800 pixel resolution, which offers at least 50 per cent more clarity than the iPhone's 480 x 320-pixel resolution. On the front of the Nexus One are four control buttons and a trackball for navigation. On the back, there's a 5-megapixel digital camera, complete with flash. The Nexus One is also remarkably thin at 11.5mm, compared to iPhone 3GS' 12.3mm. Having said that, the Nexus One is no iPhone. Somehow, Google forgot that what made the iPhone so popular wasn't just that it was a good smartphone, but it also looked like a fashion statement. The Nexus One is available directly from Google at www.google.com/phone for US$529 (HK$4,100). Pros: high resolution 3.7-inch Amoled display, 1GHz processor, Android operating system, thin Cons: it won't turn the heads of your iPhone-owning friends
