This article blames the author for not having a Kindle version of her book.

That is a very simplistic view of what it takes for some authors to be able to sell Kindle editions (I used to work in that exact field) --

* their contract with the publisher may give all digital rights to the pub. This is the case surprisingly often. Depending on the publisher's priority or digital strategy, a kindle edition may take forever.

* Royalties may be different fir digital editions, eg the publisher may want to take a much bigger cut since they don't have to pay for printing, distribution, etc. If the author doesn't like that, it can seriously delay or halt digital publication.

* Agreements with other dist. channels may prevent a Kindle edition. File under either 'digital strategy' as above or 'publisher greed/stupidity.'
