Unveiling Amazon‘s Kindle Fire HD at a press event earlier today in Santa Monica, California, CEO Jeff Bezos wasn’t shy about the device’s capabilities: “We haven’t built the best tablet at a certain price,” he asserted. “We have built the best tablet at any price.” The Kindle Fire HD comes in two versions, an 8.9-inch boasting 1920 x 1200 resolution with a TI OMAP 4470 processor, built-in camera, dual stereo speakers with Dolby Digital Plus, HDMI out, and at least 16 GB of storage; plus a 7-inch Kindle Fire HD that features most of the same specs as its big brother, the primary difference being the 1280 x 800 resolution, similar to the Nexus 7. Another benefit, the 7-inch Kindle Fire HD is optimized to deliver 11 hours of battery life. Each represents the first tablet to use dual-band (2.4GHz, 5GHz) MIMO technology, which Amazon says makes the device’s WiFi 41 percent faster than the latest iPad. The 7-inch Kindle Fire is priced at $159 and ships September 14th (pre-order it here); the 8.9-inch version starts at $299 and is scheduled to ship on November 20th (pre-order it here); and finally the Kindle Fire HD 4G LTE, with a $50/year data plan that offers 250MB/month, starts at $499 and is also scheduled to ship November 20th (pre-order it here).
