It's anecdotal, but I live in an apartment and while most of the WIFI networks are password protected, not all are.

My Wi-Fi isn't. I live about 2 miles away from my closest neighbor, so it was an inconvenience.

The trick was finding TV's and what not that don't need an Internet connection. Vizio was the only brand I could find that still had just dumb tv flat screens, believe it or not.
