I do still like books, though I find for technology topics my Safari Online subscription is way more useful than buying individual books. I'll have a book on my virtual shelf for a few weeks, dart around in it gleaning what I want, then I swap it. I not only avoid the build up of obsolete paper books, but I'm not having to struggle with the "should I buy it, which is the best, is it really worth $39 when I have blogs" type purchasing decision.

The great books will sometimes be bought outright, but by then I know well what I'm getting.
