Well, yes and no. In some cases, yes, the ebook is outselling the pbook. Should you be doing an ebook version of your book? Absolutely... sort of. It depends on the kind of book you are doing. Ebook readers still have a lot of limitations, so you have to look at a number of factors before deciding. If your book is fiction, then the answer is absolutely yes. If it's a complicated math book, well, that could be enough of a challenge that you should wait until the technology is there.
But in all cases, it's my humble opinion, that as of today anyway, you should do both a print book and an ebook because limiting options loses sales. And if you are doing that complicated math book, maybe you can do a less complicated short piece that could be done as an ebook to make it a supporting piece.
So, we can make that ebook for you, yes. But while you're at it, lets do a lovely print book too, because some of us still prefer "real" books.
