After nearly a decade of rumors and speculation, Apple's finally unveiled the iPad. It's a half-inch thick and weighs just 1.5 pounds, with a 9.7-inch capacitive touchscreen IPS LCD display, and it's running a custom 1GHz Apple "A4" chip developed by the P.A. Semi team, with a 10-hour battery life and a month of standby. It'll come in 16, 32, and 64GB sizes, and it's got the expected connectivity: very little. There's a 30-pin Dock connector, a speaker, a microphone, Bluetooth, 802.11n WiFi and optional 3G, as well as an accelerometer and a compass. There's also a keyboard dock, which connects underneath in the portrait orientation, and support for up to 1024x768 VGA out and 480p composite out through new dock adapters. The device is managed by iTunes, just like the iPhone -- you sync everything over to your Mac. As expected, it can run iPhone apps -- either pixel-for-pixel in a window, or pixel-doubled fullscreen -- but developers can also target the new screen size using the updated iPhone OS SDK, which is available today.
