Anyone selling the ebook version at $9.99 or so is taking a small loss. Then again, a retailer selling the hardcover for $16 with free shipping is likely taking the same size loss....
That said, I'd say it's a good thing that ebooks are starting to make a noticeable dent in sales figures. And heck, that's a bunch of trees that didn't have to get cut down for those 100,000 copies...
