SLIDESHOW: Worst Product Flops of 2012
5. Nokia Lumia 900
The Lumia 900 was introduced at the Consumer Electronics Show back in January, but sales were never able to take off. Although the phone debuted at just $100 with a two-year contract, AT&amp;T soon dropped the price to $50 to improve sales - and even that didn't work. A consistent criticism of the phone was that its screen resolution was weaker than competitor phones and, more importantly, that the Microsoft's Windows operating platform had a shortage of apps. By November, Nokia started selling the Lumia 920, and early predictions for sales of the newer version were mixed. Nokia, once the world's largest mobile phone maker, has steadily declined in recent years, losing significant market share to companies such as Samsung and Apple. In the third quarter of 2012, Nokia's market share of smartphones was just 4.3%, according to Gartner Research.
