nokia-lumia-800Nokia has bet the house on the Windows Phone 7 mobile operating system, and the first fruits of Nokia’s relationship with Microsoft were finally shown today with unveiling of the new Lumia 800 and 710 smartphones.

Between the two, the Lumia 800 is the flagship device with the better design and internals. Its design looks and feels expensive with a solid body that decidedly European. The Lumia 800 features a 3.7-inch AMOLED screen, 1.4-GHz single-core processor, 16GB of internal storage and an 8-megapixel camera with 720p HD video capture. Microsoft also provides owners with an additional 25GB of free cloud storage using its SkyDrive service.

The Lumia 800 and 710 are also some of the first devices to run Mango, the latest version of the Windows Phone 7 OS. Mango adds more than 500 new features, including direct social networking integration, contact groups, live tile notifications, Xbox Live improvements, Bing indoor maps, and an Internet Explorer 9 browser that’s the same as the desktop version rather than a mobile version. Those features, along with Nokia-specific apps like Nokia Maps and Nokia Drive, help make the Lumia 800 feel like the best phone Nokia has manufactured in many years.

Take a look at the lengthy video below that shows off many of the best things the Lumia 800 has to offer.
