I don't regret buying a brand new hardcopy of this book... it's the best textbook I've ever owned. I find it really tedious to read a book like this with lots of typeset math on a computer screen.
I bought the hardcover too. After I had already printed out the draft and read it multiple times.
I really wish they had a kindle version, though. Or some electronic version. It really seems primitive not to be able to run a search on something I've read,. Or bookmark. Or tag sections. And where's my hover car?

The book didn't include Chapter 30 - "MAXIMUM ENTROPY: MATRIX FORMULATION"
Opening in adobe seems to work out better for me.
