Amazon's Kindle Fire is being sold at a loss to heat up competition with Barnes & Noble and Apple, IHS iSuppli estimated Friday. Based on a list of known and expected components, it believes the seven-inch mini tablet costs $209.63 in raw parts and manufacturing, or about $10 less than its $$199 asking price. A high-quality IPS-based LCD at $87 is a large part of that cost, while adding the dual-core TI OMAP processor and other mainboard components pushes it up by another $70.40.
