Today Phil Schiller took to the stage at the Yerba Buena Center for the Arts in San Francisco, where he announced the long-expected iPhone 5. The casing is made entirely of glass and aluminum, and it's 7.6mm thick, which is 18% thinner than the iPhone 4S. It weighs in at 112 grams, which is 20% lighter than the 4S. Schiller confirmed that the iPhone 5 has a 4" display, with a resolution of 1136x640. It's a 16:9 aspect ratio. The screen is the same width as a 4S, but it's taller. To accommodate older apps, they either center the app or add black bars to make it look right. The new device also has LTE support. Tim Cook spoke earlier about the iPad, making some interesting claims: "Yes, we are in a post-PC world." He also claimed 68% tablet market share for the iPad, and says iPads account for 91% of tablet-based web traffic. The event is continuing, and we'll update this post as further announcements appear.
