Nokia Lumia 800

The Nokia Lumia 800 is the Finnish firm's first handset to use Windows Phone, and it's been a quite success - a million devices have been sold worldwide so far.
The size, shape and weight of the Nokia Lumia 800 provides a quality feel, and is a unique shape compared to many other phones on the market.
The GUI feels intuitive with a very impressive speed of response, providing a continuity of feel between applications.
Essentially, the Nokia Lumia 800 takes the best of Windows Phone - Xbox Live integration, fantastic Office tools and a clever tile-based user interface - and adds in a great quality screen with a nice-feeling chassis.
