I'm sure that I've seen 35mm cameras made during the 40's and 50's that used a similar method for focusing. I know there
were a number of 110 cameras that used that system.

I've never see it advertised as such, but I can believe that putting the 'tics' on the lens barrel to show what's in focus at different f-stops could have been marketed that way. It's sure a lot more convenient than carrying around a hyperfocal chart. :-)
A fast way to go with a wide angle lens P&S camera.
I don't usually have to worry too much with wide angle lenses, since they have very deep fields of focus compared to the 200+ mm lenses I'm usually using. I have used it at the track when photographing race cars with long lenses.
