Top 10 Smartphones and Tablets of Mobile World Congress 2013
Nokia Lumia 520
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.
