With its Lumia 520, Nokia is bringing the premium features found on the Lumia 920 to the budget phone market. For what is expected to be a relatively low price, the Lumia 520 will include a 1-GHz dual-core processor and 512MB of RAM. Its 4-inch screen won't be the sharpest on the planet, but hardware isn't the point of this phone. What makes this smartphone a hit is that it will be the cheapest Windows Phone 8 device around.
