Unlike classical life, here it is cheaper to run it than to read about it in a book, never mind the phelora of tutorials online, free documents from vendors. Compare it to riding a horse or driving a car, where the book is cheaper. However, learning by doing is more vivid than reading, real horse sweat, wind in your hair, and error messages when you forget a keystroke.
There is a free kindle library and free kindle readers, so free books are not completely foreign any more. Are there other free libraries?
