As of today, in addition to Kindle, 'Merdeka' is available for purchase and download in the following key formats: Epub, Online Reading, PDF, RTF and several others. The book can be purchased through Smashwords. What does this mean? Now you no longer just need a Kindle to properly enjoy the eBook. If you buy the book at Smashwords the guidelines for format choice are:
Epub (Apple iPad/iBooks, Nook, Sony Reader, Kobo, and most e-reading apps including Stanza, Aldiko, Adobe Digital Editions, others)
Online Reading (HTML, good for sampling in web browser)
PDF (good for reading on PC, or for home printing)
RTF (readable on most word processors)
The downside (or upside depending on your perspective) is that the Smashwords edition is DRM (Digital Rights Management) free, giving much more flexibility to purchasers.
A further update will be posted once Smashwords has made the book available to key online retailers. There is no change to the Kindle Edition in the Amazon stores, which is available as before.
