Perhaps, but that only applies for the minority of people who read eBooks who can actually do conversions. The vast majority of people who read eBooks won't even know what kePubs are, nor probably care. And why the hell does Kobo insist on using kePubs anyway? The ePub format is good enough as is without forcing another proprietary format on readers. I like Amazon because of Whispersync and their whole system, but I'm also one of those who wish they would have gone to ePubs rather than KF8. The difference of course is that Amazon sells more eBooks in the USA market than all the other eBookstores combined, so Kobo is a SMALL store which will have little impact on the North American market or the world market. Few consumers will therefore buy their proprietary kePubs. Amazon, like it or not, sells 2/3 of the eBooks sold in the USA. Their proprietary KF8 and mobi impact the market in a huge way.
