There was a story in the papers recently, that the prevalence of GPS and SatNav's has put the Ordnance Survey's maps in danger of obsolescence. Obviously, my Media Bullshit Detector starter pinging, but there is a core of truth in the story. More's the pity, as OS maps are a fantastic resource, and I love them.

Bonus - Necessity is the mother of invention.
