Also, who is the target audience and what are the plans for reaching it? I don't think there are many people who are willing to invest time AND money into a book like this while still not having read the sequences (available freely on the web, and also in all kinds of e-book formats).

For the two use cases I imagine at the moment:

• giving it as a gift as an introduction to rationalist stuff feels better with a physical book indeed. Yes, there is a difference between buying an e-book for yourself and downloading the same stuff for free, especially in terms of motivation to actually read it, but on the receiving end e-books still might feel like being sent long pdf-s with a label "you should definitely read this", in addition to the e-book gifting weirdness (I might be wrong, I never did such a thing before).

• buying it for yourself, to be able to put it on your bookshelf. Obviously, also much harder to do with an e-book.

(I usually prefer e-books to dead-tree versions, but then I had nothing against reading the Sequences on the web either.)
