Aaron takes a look at the Nokia Lumia 820 on AT&T. While some would consider it to be a "mid-range" device due to the $49.99 price tag, the Lumia 820 packs specifications that any mainstream user would enjoy, including a 1.5 GHz dual-core Snapdragon S4 CPU, 4.3-inch display, 8-megapixel camera with 1080p HD recording, 1,650 mAh battery, and 4G LTE. It's priced well, but with holiday promotions from various carriers, a better phone may be close to the same price. Is it worth buying? Part 1 of 2.
