With the shared unveiling of Nokia's Lumia 720 and Lumia 520, the company's running flush of Windows Phone 8 models was complete. All WP8 handsets we've reviewed essentially fit into two distinct tiers based on shared core specs. That begs the question: why come out with two new models now when both share the same SoC, amount of RAM and screen resolution as the established Lumia 620 and HTC 8S? Obviously, there are differences in design, cameras, display tech and all the other bobs and bits that create the 720, but is it worth the significant markup over the 620, and more than double the price of a 520 or Huawei Ascend W1? Enough with all the rhetorical questions -- join us after the break as we find out exactly what the Lumia 720 has to offer.
