I like paper books more than e-books, but which one I read depends on the type
of content.
I prefer digital version for technical stuff, because it's often hard to get
hardcopied version (e.g. for documentation) and the content will most probably
expire in a year or two. The only technical books I buy in paper are those
that don't expire, like "Introduction to Automata Theory, Languages, and
Computation" (Hopcroft, Ullman).
On the other hand, I read novels almost exclusively on paper.
It all boils down to this: I only have so much spare place to keep paper, so
I keep in paper only those that I will want to keep for ten years.
