My home AP isn't protected. I don't want the overhead of WEP (which causes a performance hit). My PCs are running current patched XP with a software firewall, so its remote that you're getting in. I could care less if someone wanted to use my cable company's bandwidth. And from what I've read, hacking WEP is pretty trivial for someone that really wants to get in.
Our Work AP's aren't protected either, but the hitch is that they are all attached to our "bastion" subnet, which is where our internet/external servers sit. To use wireless, you have to VPN in, even though you're in the building. Again, I think out telecom guys aren't concerned if someone wants to use it for some freeloading surfing.
