Going Wireless

We’re finally getting a wireless router at our house (Amazon just notifed me that it’s been shipped). I’m really excited, since it will free up my laptop. (I currently use it at the dining room table, with a cable running from the office, through the hall & into the dining room plugged into the laptop.)

My question to my friends out there is: should we set up a password to access the wifi or leave it open? My beliefs push me to leave it open, but I’m wondering if there are consequences to leaving it open that I don’t want to deal with. I realize that anyone who really wanted to could certainly break into a protected network, but I also doubt anyone like that is going to be hanging around our neighborhood. So, open or not?
