With Lumia 900, Nokia and Microsoft Bid for Smartphone Relevance LAS VEGAS - What is it with Jan. 9 and smartphones? At a news conference Monday afternoon here at the International Consumer Electronics Show, Nokia, as expected, introduced the Lumia 900, a smartphone that the Finnish cellphone maker and its software collaborator, Microsoft, hope will finally lead to redemption in the smartphone market. It's a coincidence, but nevertheless interesting, that five years ago today, Apple announced the first iPhone at Macworld in San Francisco, as the blogger M.G. Siegler pointed out earlier Monday. Of course, it's far too early to say whether the Lumia 900 will be a hit and, even if it is, the device most likely will not have the eye-opening effect that the original iPhone did. Nokia and Microsoft both want to establish Windows Phone as a "third ecosystem" in the smartphone business that can compete with the iPhone and Google's Android operating system, attracting as much interest among independent developers as those technologies have. The two companies have a long way to go. But the initial buzz about the device among gadget watchers has been positive. Stephen Elop, the chief executive of Nokia, said the company had put all of its best technology into the phone. "It's the first real Windows Phone built for and designed for the North American market," he said. The device has a slim case with rounded edges on the side and a bold, bright 4.3-inch screen that is bigger than the iPhone's. Nokia bragged about the superior technology in the Lumia 900"s camera, which allows for better photographs. The product will also run on AT&T's 4G LTE network, its fastest wireless data network. As it did with the original iPhone, AT&T will exclusively sell the Lumia 900 in the United States. Mr. Elop wouldn't said when the phone would be available in the coming months. He did not say how much it would cost either, though he noted that Nokia's "intention is to be quite aggressive" with the pricing of the phone.
