I prefer to read some sorts of technical books on paper. I feel disheartened coming out of a bookstore with nothing but 500 pages of facts that no one will care about in 10 years. If I find myself holding a copy of "Coding FadLanguage for Dullards," I pick up "The Political Writings of Thomas Jefferson," hoping that if I read both, I won't get any dumber on balance. Sometimes the later has to wait. Sometimes the former expires.
