I recently heard about the media company Inkling. Here's some information from a spokeswoman:

For more information, your readers can visit this link for Superstar Knitting. We have more Stitch 'n Bitch books, this is the link for them! --I read the sample chapter from Stitch 'n Bitch Superstar Knitting and I really liked it. It was clear and easy-to-read on my computer screen, the illustrations looked great, and having links within the text made it easy to learn more about any particular subject. I'd be curious to see it on a phone, but I bet its performance on an iPad is pretty great, too. Just another option for a book that won't weigh down your knitting bag.
