Aaron reviews Nokia's flagship Windows Phone, the Lumia 920.  Featuring a 1.5 GHz dual-core Snapdragon S4 CPU, 4.5-inch PureMotion HD display, 8-megapixel camera with 1080p HD recording, 2,000 mAh battery, and 4G LTE.  It can be had at AT&T for $99.99, and comes in white, black, red, yellow, and blue.  It's priced incredibly well, but it's joining a myriad of other Android and Windows Phone devices this month.  Can it go head to head with the other flagship devices on the market?  Part 1 of 2.
