For the average home, I agree with Oast. I'm far from concerned about my neighbors cracking their way in. And as far as pros driving around seeking out signals, I can walk my laptop out to my sidewalk and lose signal, so I'm not worried. If I lived in an apartment building with a bunch of strangers, I'd probably be more concerned.
I use WPA-PSK, not WEP, on an 802.g network if anyone wants to pull a drive-by. My house is the one with the with rusted tin porch roof.
