Okay. Maybe in Latvia things moved a bit slower. I am only speaking from my experience in the USA and from my experience selling these devices.
In 2004, when I started dating my wife, we drove around my town with a laptop and a WiFi PCMCIA card and detected over 200 insecure WiFi networks. I used this as a marketing campaign to secure people's home networks. I don't remember how many secure networks I found back then though.
