Sorta on the same subject ... remember that crazy lady who lived with me a year ago, imploded & ended up in jail? Well, I haven't been able to find my tomtom GPS ... assume she stole it. So Walmart had some on sale so I bought one ... actually an upgrade from what I had before. I got it home and programmed my home address in. BUT ... where the satellite "sees" me is a quarter-mile from my house!
That doesn't give me a whole lot of confidence that it will get me where I want to go. I mean, I want to go WHERE I want to go, NOT within a quarter-mile or so. Y'know what I mean?

"Almost" is good enough in horseshoes and hand grenades, but not for a GPS.
