any word on this coming out in pdf? thats the version I strongly prefer for my ebooks
for novels where I'm reading for story, I use a kindle but for textbooks, I strongly prefer pdf
The HTML version can be "printed to PDF".
There is no "manually layouted" PDF available however. That requires manual typesetting the whole book, which is weeks or months of extra work. I will do that if I ever make it into a physical book. At that point an official PDF would also become available.
That said, many of my readers like having the HTML version in a window next to their code window. I think it is the best experience on a computer. On the iPad I would probably read the EPUB. But if you prefer PDF, then print the HTML version to PDF.
