Aaron does a full video review of the Apple iPhone 5.  Featuring an Apple A6 dual-core CPU clocked at 1 GHz, the iPhone 5 sports a 4-inch Retina Display (326 ppi), 8-megapixel camera with 1080p HD recording, 1,440 mAh battery, 4G LTE, and iOS 6.  It's available now at Verizon, AT&T, and Sprint.  For iPhone fans, it's a great upgrade - and it's a high-end phone that's worth recommending to many.  But keeping the big picture in mind, iPhone no longer commands the wide lead it once had in the smartphone market.  There are a ton of great high-end Android and Windows Phone devices that offer equally compelling value propositions.  Is iPhone 5 worth your hard-earned money?  Part 1 of 2.
