This fell a bit flat for me. From the title and the opening paragraph I formed an idea of where the story was going to go, and when it moved too slowly, insufficiently weirdly and without any conflict, I felt quite disappointed.
It's interesting that more reactions to this story appear to have been "I could write something exciting in a similar style" than "This story nails the Fantasy SatNav concept so well that there's no point in competing against it" -- it gives me the impression that more people were thrilled by the concept than were awed by the execution.
I liked some of the little touches that gave the story its atmosphere, though, and the reading was sonorous.
