HotHardware.com posted a review on the Nokia Lumia 920 Windows Phone 8 smartphone

In a sense, it feels like Windows Phone 8 is Microsoft's first real foray into the smartphone space post Windows Mobile. Of course, Microsoft made a concerted effort with Windows Phone 7, but there's something vastly different about version 8. WP8 borrows from the underpinnings of Windows Phone 7, but there are so many differences in the operating system -- along with its incompatibility with WP7-class hardware -- that it feels like we're evaluating an entirely new product. And in reality, we are.

Nokia's Lumia 920 is one of the first Windows Phone 8 products, along with HTC's 8X, in a holiday smartphone lineup that has become amazingly crowded. Microsoft is trying its best to carve out a niche despite Windows Phone 8 being overwhelmed on shelves by the iPhone and Android-based products. But Nokia's expertise in the hardware business shines through in the design of this particular phone. A lot is riding on the success of the Lumia 920, not only for Nokia but for Microsoft's mobile team as well.
