Microsoft launches Lumia 950, 950XL, 550 smartphones, Surface Pro 4 tablet

Microsoft Corp unveiled a new line of Lumia smartphones, a new Surface Pro tablet and an updated version of its wearable fitness tracker, Microsoft Band, that will run on Windows 10, its latest operating system.

Windows 10, launched in July, is part of Microsoft's push to win a bigger share of the market for tablets and smartphones, now dominated by Apple Inc and South Korea's Samsung Electronics Co Ltd.

Microsoft unveiled three phones at an event in New York. The Lumia 950 and 950XL will have starting prices of $549 and $649 respectively when they go on sale in November, while the Lumia 550 will cost $139 when it becomes available in December.

The Lumia 950 includes a 5.2-inch display and a hexacore processor, while the larger Lumia 950 XL has a 5.7-inch display with an octacore chip. The specs on the budget 550 had not been released as the event continued.

The new Surface Pro 4 tablet - a larger but thinner and lighter version of the Surface Pro 3 - runs on 6th-generation Intel Core processor and has 16GB of RAM and 1TB storage.
