The Nokia Lumia 1520 joins the fray of gigantic smartphones like the HTC One max and Samsung Galaxy Note 3.  Featuring a 2.2 GHz quad-core CPU, the Lumia 1520 packs a 6-inch 1080p HD display, 2 GB of RAM, 32 GB of internal storage, 3,400 mAh battery, 20-megapixel camera with Carl Zeiss lens, and Windows Phone 8.  There's a lot to like about the phone, and it's by far the best spec'd Windows Phone device to date, with internals that compete with the best that Android has to offer.  The biggest downside is the missed opportunity in the software department - for a device with such a large display, there's aren't any bonuses that truly enhance the experience.
