> Kindle does support mobi, but you have to convert epub files (this can't be done through your Kindle email address' convert ability for some reason). I think the reason is they don't want to make it too easy to buy ebooks elsewhere and read them on the Kindle. Having to use something like Calibre to convert epub to mobi before sending it to a Kindle is just enough hassle and requires enough comfort with technology to make most stick with the easier option of buying ebooks from Amazon.
