How many of you have business cards-Why or Why not?

I have noticed a trend lately that is extremely disturbing to me: Lots of small business owners and authors don't have business cards. Before I go into my thoughts of why these things are vital to book sales, and just sales period, i'm curious to know how many of you have business cards and how many of you don't, why or why not?
