Amazon's introduction Thursday of the Kindle Fire HD opened two new fronts in the tablet wars. The 8.9-inch Kindle Fire HD is expected to compete with Apple's new iPad, and the Kindle Fire HD 7-inch model will do battle with Google's Nexus 7.

With the release of its two most powerful tablets to date, Amazon puts itself squarely in the tablet-war crossfire between Apple and Google.
