Right now, wireless is incredibly insecure. I was in a security conference that just happened to be right next door to a building we had some Cisco wireless units in. The guy brought up his laptop with wireless card, started up his sniffer and we started seeing some of our packets flying by. It was a little embarrassing. That's the "real" reason I am not interested in wireless. I have Cat5 connections all over my house (except the bathroom) so it's not that big of a deal for me.
