Avid physical book reader, particularly for anything professionally related. For me, there is no substitute for a physical book. They are extremely durable, inexpensive, reliable, allow me to write in them (e.g. corrections and ideas), highlight in different colors, can be set on a book holder next to me for reference while coding, be easily shared, be easily gifted, can have several open at once for reference, last longer than I have been alive, etc. There is a beauty in their simplicity and barebones functionality. TL;DR Give me physical books or give me death.
