Nokia Lumia is my smartphone and I am really happy with its performance. It comes with the latest Windows OS and the 8 MP camera is excellent. Usability and user interface give it a top of the line phone experience. Also its got killer social networking integration across various platforms.
The AMOLED touch screen makes the visual a treat. Even though the phone is expensive, it is well justified for the features and the discount given by Homeshop18 is also superb.
