Agreed, I really don't like physical technical books. If an epub was available, I would have spent the time writing this comment by filling out my credit card details in stead.
Same here, I would immediately buy this new version (I bought the first one) if it were available electronically.
I stopped buying paper technical books, they are never around when I need them. I also like to read them on my iPad, phone and laptop at different times.
My money now goes to publishers (like O'Reilly) who support my workflow.
