Nokia enters the tablet wars Nokia has unveiled its first tablet computer and two new large-screen smartphones. They will be part of new owner Microsoft's push to become a leading player in consumer devices. The tablet - which has a 10-inch screen - and the so-called phablets - with 6-inch screens - are among the last products the Finnish company developed before deciding to sell its handset business to Microsoft. They use Microsoft's Windows Phone operating system and will face tough competition from Samsung and Apple. The tablet will also compete with Microsoft's own Surface 2 and Surface Pro 2 devices, which just went on sale. "Despite a more affordable price, the respective positioning of Nokia's tablet versus the Surface 2 is not obvious and will have to be dealt with after the Nokia acquisition," Forrester analyst Thomas Husson said. The new devices will help Microsoft to increase the number of Windows users, but Husson said he expects it to remain a long way from "a significant installed base of consumers." Nokia, once the global leader in mobile phones, arrived late to the smartphone race and has struggled to catch up with Apple and Samsung.
