An Amazon rep shows us the Kindle Fire and dishes on specs:
The Kindle Fire has a Gorilla Glass-protected, multitouch-capable IPS display, a TI OMAP4 dual-core processor, and at 14.6 ounces (413g), a pretty lightweight frame. The resolution on that screen is 1024 x 600, same as on RIM's BlackBerry Playbook, and the Kindle Fire's physical dimensions are 7.5 x 4.7 x 0.45 inches (190 x 120 x 11.5mm). There's 8GB of built-in storage and the battery's rated to last for eight hours of continuous reading or 7.5 hours of video playback (with WiFi switched off). A 3.5mm headphone jack is naturally included as is a pair of top-mounted stereo speakers.
