I bought a copy. Nice book! The format of the book seems kinda odd thought. This is a screenshot from my iPad Mini with Readmill (eBook reader): https://dl.dropboxusercontent.com/u/947269/IMG_0053.PNG
Also, I think the best use of the book is to read it on a PC / Laptop and copy/paste to try the examples as you go :)
But, as always, your mileage may vary!
