Looks like $109, $139, and $189 for the eink Kindles without the special offer ads.

Still no ePub support, even on the Fire. My existing ebook library still can't move onto a Kindle natively.

Very interesting move though with the Fire. I do think this will be the first tablet to properly challenge the iPad in non geek circles. They have a good amount of content to offer, a well known name from the existing Kindles, and a CEO who isn't likely to kill the product a month after launch.

What will also be interesting to watch is the potential Android tablet fragmentation this brings. Honeycomb is still closed, meaning the Fire most likely is using the older open 2.x series versions of the OS. (I highly doubt Google would have certified the Fire and granted Amazon access to Honeycomb). Will app authors spend time making Honeycomb optimized tablet apps, and 2.x apps targeted at the Fire and Amazon store? Guess that will all depend on how well the Fire sells to end users.
