I think business cards are important for advertisement. I always take one from people I'm thinking of doing business with to keep in my wallet to call if needed. Even with all the new ways to advertise, business cards are still a good idea.
They're not essential, as in you could get away with not having business cards if you have established online profiles (depending on your industry of course) but having a well designed card really gives off a good first impression and we all know how quick people are to judge.
Definitely the Darkside. I could never keep up with the Jedi Code. "There is no emotion." That's like standing in front of a hot and fresh pizza and saying it doesn't exist. That brings me to my second point. Jedi aren't allowed to love. I love pizza, I can't help it. It's soooooo good!!
