I've also never really pirated books, because there's very nice, legit and convenient sources to get them - namely physical, DRM free ones also available in public libraries... (only exception: George R.R. Martin when I didn't have 200€ to spend, because the library was reserved for years to come).

This changes for movies, where I try to buy Blu-Rays nowadays but I won't let copyrightholders kill my physical drive for it, so if they think they don't want me to give a suitable, high-def media I can effectively do whatever I want with: piracy it is.
