I believe in all digital books. It lacks that real feeling of a book i.e. having paper/something physical, but for tech books it's nice to have them digital for a couple of reasons:
1. Copying code from the book to an editor is MUCH easier.
2. Books take up physical space and it's hard to be mobile when you have to pack/unpack and move heavy things that you aren't going to be constantly using. I define things that I constantly use that are like my computer, laptop, kettle.
3. Cmd/Ctrl + F - I can't live without it even with a digital index.
