Amazon announced three new kindles today, two of which use E Ink displays. The new Kindle Touch e-readers feature 6" Pearl E Ink displays and an infra-red touch sensor. The $79 non-touch Kindle 2011 is a streamlined version of the older Kindle 3 - with only 5 physical buttons (beside the next/prev ones, anyway). The Kindle Fire is a $199 7" IPS-LCD tablet/e-reader.
The Kindle Touch will launch on November 21st, but you can order it today. The Wi-Fi version costs $99 with screensaver ads and $139 without ads. The 3G version costs $149 (ads) or $189 (ads-free). The Kindle 2011 is shipping now: $79 for the ad-supported version and $109 for the non-ads variant. The Fire will launch on November 15th for only $199 - you can pre-order it now.
Amazon also discounted the old Kindle 3 (now called Kindle Keyboard): The Wi-Fi Kindle 3 is $99 with ads (down from $114) and $139 without ads, while the 3G one is $139 with ads (down from $164) and $189 in its ads-free model.
