This has probably been discussed to death, so feel free to post a link to a page where my question has already been answered.

I just published my first ebook to Amazon and iBooks, but I want to sell it on my website, too. I've signed up with E-Junkie, which seems really user friendly.

But I wondered if I should just sell my epub as is, or should I offer different versions for different readers?

I don't own a Kindle, but my understanding is that you can't read anything but MOBI files in a Kindle, right?

Epubs work fine in iBooks. My understanding is that any epub specifically formatted for iBooks can't legally be sold anywhere but on iBooks. The only advantage to iBooks formatting is "multi-touch," and from what I've read, that sounds like a pretty worthless feature.

So I'm guessing I should offer the original epub for iBook fans and a Kindle version form people who own Kindles. What other formats do you sell your epubs in?
