Amazon has lowered the price of its 8.9-inch Kindle Fire HD tablet it released last year. The Wi-Fi model starts at $270 (reduced from $300), and the 4G LTE model--the one with the $50/year AT&T data plan--now starts at $400 with offers. Availability is also expanded to Japan and Europe. While Amazon's fork of Android on its Fire tablets has improved, many users will still want to wait until a stable CyanogenMod release is issued for the Fire HD. Amazon's tablets use TI OMAP chips, which make them easier to mod than tablets with chips from Nvidia, HTC, and Samsung. Still audio and camera support are the toughest nuts to crack for custom firmware.
