Too Soon To Grade: Unveiled just last month, the iPhone 5 didn't break a lot of new ground. Its 4-inch screen was a little longer than its predecessor's; and the device itself was a little lighter and thinner. And the iPhone 5's best upgrade, 4G LTE, is hardly unique among high-end smartphones.
That said, the latest iPhone is a beautifully engineered device, and one of the best consumer mobile phones your money can buy. Sure, this year's model isn't an essential upgrade for iPhone 4S users, but it's a solid step up for folks carrying around an iPhone 4 or older. Will the iPhone 5 be a blowout success like its predecessors? Probably, but we won't know for sure until Apple reports its holiday quarter earnings in January.
