Just to add to the HN echo chamber, I bought and love the 1.5 ebook, but the lack of a digital version for this new edition means I won't be updating. When I am building new projects I often find myself using ctrl+F to search for specific mentions of variables or settings. A print book adds "stuff" to my life, gives me another thing to carry between work and home, and makes it harder for me to find the information I need. But I understand that as a member of the minority (i.e. ebook purchasers) I am in a strategically disadvantaged position and accept that. I can live without it.
