Amazon originally designed and sold the Kindle reader to encourage their sales of E Books I believe. So why do they not offer their E Books in both their current Amazon exclusive formats and E pub format as used by practically every other current reader, tablet and reading application in the world?

Their readers should also support the E pub format. I would think that this would further boost their electronic book sales, particularly overseas, as well as make customers happy. They could also make their E Book format public domain or freely licensable for other reader manufacturers, again potentially increasing their electronic book sales. The fact that we currently have two major E Book formats, mutually incompatible without conversion, seems to me to be kind of stupid. Amazon formats and readers practically dominate the USA market and the rest of the world reads Epubs. This might also increase Amazon reader sales overseas.

I realize for sophisticated readers there are various work arounds to convert files back and forth between formats but for the average person who just wants to use a reader for reading a book this may not be an option. Making readers that are compatible with both common formats seems to me to be a no brainer. I bet that Amazon could enable E pub compatibility with a simple firmware update.
