The Killer iPhone

Fans and analysts raved over the $199 phone's videoconferencing feature, applauded its slimmed-down design, and looked forward to a promised new era of hyper-multitasking. The new iPhone is built not just to compete with other phones but to keep pushing the boundaries of the Apple universe. While other phonemakers have gone megapixel-mad - Nokia, Samsung, and others boast cameras in the 8 to 12 range - Apple has held steady at five megapixels. Additionally, iPhone 4 has a front-facing camera that is central to its marquee feature: Video calling. Apple boasts that the iPhone 4's front and back glass casing is 30 times stronger than plastic, though analysts say it is only slightly sturdier than the stuff used for the past two generations of iPhones. The newly renamed operating system, iOS4, finally brings multitasking to the iPhone with the ability to organize apps into folders by category, such as sports.
