I still go for dead tree on most subjects I'm interested in. I rarely read them all the way through however. For me they're mostly meditative aids that help me sort out my thoughts when I run into a wall.

When I'm stuck I can only bang my head against the problem for so long until I get frustrated. Having a dead tree version lets me completely leave the computer behind. Reading about anything related helps my mind reorganize and regroup. After an hour or so with my nose in a book I have at minimum an idea of something new to try.

Also, the book store I go to is in the same building Bioware was based out for many years. It's just a reminder to me of success that was born just a few blocks from me.

I've stopped buying books on specific tools / programming languages. I can almost always find better information online. (Ruby is one exception: you pretty much need the pick-axe book). safari.oreilly.com is a great resource when nothing else is available. However, I still regularly purchase books on "higher" topics like algorithms or mathematical abstractions, the sort of books that I'm more likely to find in my university's bookstore than at Barnes & Noble.
