TheVerge - Nokia's family of Windows Phone 8 handsets just continues to grow. The Finnish smartphone maker is pushing its Lumia devices into the low- and mid-range with devices like the Lumia 620 and 520, but a surprising entry in the form of the Lumia 720 makes Nokia’s budget smartphones a lot more interesting. While the Lumia 920 includes high-end specs and an impressive camera, it's a bulky and heavy device that doesn’t appeal to everyone. Likewise, the Lumia 820 lacks any wow factor with a bland and hefty design and mid-range specs. But the 720 appears to combine the right size with the right design, something the middle of Nokia's lineup has lacked.
