I use ebooks and physical books, but I am regretful of some physical books mainly because: 1) They take a lot of space. I have bookshelf's full of them. 2) They can get damaged by humidity and mold. 3) I am prospecting travelling/moving/migrating, and I will likely sell/donate my books in this case. That being said I want to support the authors I read, and wish I could buy the digital book directly from the author (100% of the money goes to him/her), and get an electronic copy.
