The Nokia Lumia 900, which was launched at the 2012 Consumer Electronics Show (CES) on Monday, is expected to provide tough competition for all iPhones and Android-powered devices. The company believes the latest Lumia could take a large bite out of market shares from other smartphones and could be considered the industry's benchmark in coming days.

Nokia's flagship Windows phone - the Lumia 900 handset - was described as iconic, beautiful and fast by Chris Weber, the President of Nokia in North America. Additionally, the Lumia 900 is the company's first 4G LTE phone and will run on the AT&T network.

On the other hand, Apple's iPhone 4S has already received overwhelmingly positive responses from across the world. The phone has Apple's latest operating system - the iOS 5 and revolutionary features like Siri - a voice-assisted artificial intelligence and personal assistant - iCloud, Bluetooth 4.0 wireless technology and a 3.5-inch TFT Retina multi-touch display.
