This will allow me to enjoy a couple books that have images that are too small to get any of the details out of.

Although, I was now tempted by the possibility of getting technical books in the Amazon Kindle format, I was immediately disappointed that there is no way to copy text or search!

Below are some features to be added in the near future:

• Create notes and highlights
  Along with viewing the notes and highlights you created on other Kindle devices, you will be able to create and edit notes and highlights.
• Search
  You will be able to search to find a word or a sentence in the book you are currently reading.
• Zoom and rotate images
  Click on an image to see an expanded view and rotate it if desired.
