News on Kindle Reader edition: We're told that it will be in Amazon's hands by the end of this week, so availability likely this month. Note that it is in "Print Replica" format, thus readable on laptops, desktops, and tablets, etc., but not on e-ink devices like Kindle Paperwhite.
Here's how Amazon describes it:
"Kindle Print Replica textbooks maintain the formatting and layout of their print editions while also offering many of the advantages of Kindle books.
Each page in a Print Replica textbook displays words and images in the same position as the corresponding print edition, while adding features such as notes, highlights, and the ability to sync your last page read across multiple Fire tablets, Kindle e-readers and Kindle reading apps. Kindle Print Replica textbooks also have most of the same features as PDF-formatted books, including zoom and pan functions.
Kindle Print Replica textbooks are supported on: Fire tablets, Kindle for PC, Kindle for Mac, Kindle for iPhone, iPad, & iPod touch, Kindle for Android, Kindle for Samsung."
