PC World writes: "Innovative design and seamless integration between software and hardware propelled the first-generation iPhone to instant stardom. Its successor, the iPhone 3G, at once expands upon that innovation--and delivers it at half the entry price of its predecessor. The result is a classy device whose abilities continue to make it a strong choice for smartphone shoppers who value form that supports function--but less of a must-have upgrade than you might think.

Up front, Apple largely delivers on its promises. iPhone 2.0 software supports, among other things, the newly launched and eagerly awaited iPhone App Store. (Owners of first-generation iPhone can download the software for free.) A faster wireless radio loads Web pages up to three times faster. An appealing lower price makes the iPhone more accessible to an audience beyond early adopters and gadget hounds ($299 for the 16GB version in either white or black or $199 for the 8GB version--that"s one-third the price of the original 4GB iPhone that shipped a year ago)."
