It’s more about money at that point, Noumenon. When people shop for home wireless routers, they’re looking at the cheap-o $35 dLinks. Hell, anymore the ISPs are providing gateways with wireless routers built into them and controlling security from the home office. I’ve had to specifically request wired-only gateways for customers who I’ve helped to setup their home networks. That additional hardware layer of abstraction can often keep script kiddies at bay.
That's the truth. You can war-drive any apartment/condo complex and any 'burb and find a smörgåsbord of available APs. Far too many folks leave their wireless wide open.
Even up in Sandpoint, Idaho in an industrial area, I can 'see' no fewer than 8 APs, 3 of which are wide open, 2 of which are using WEP (bars of marshmallow), 2 using WPA-PSK and only one besides mine using WPA2 Enterprise.
