I guess I was asleep at the wheel, and did not realize the Kindle version has now been released.
I bought the 3rd edition hardback in May of last year, and thought I could convince myself to read a physical book--but this book is just too heavy to read!
Bought the 3rd edition Kindle book last night (already had the 2nd edition Kindle book), and it is spectacular. It is the print replica version, but I find this easier to read due to the sheer number number of tables/diagrams/schematics.
I don't necessarily regret purchasing the physical book, but the Kindle edition is so much easier to read/practical
Edit: Thought I would add that the print replica still supports searching, highlighting, notes etc.
