My roofer (in Lancaster County, PA) is an Amish man who owns a cell phone. He doesn't keep it with him, mind you, he just listens to his voice mail once an evening and returns the calls made. The next day he and his partners get driven around by a non-Amish to each job site of the day.
To use a stereotype in a positive fashion, he, like most Amish and conservative Mennonites I've dealt with, takes a lot of pride in his work and charges very little relative to other businesses.
Years ago I worked for a company that supplied medical supplies (bottles and jars etc) to other companies, the company was owned by a religious group who eschewed the use of technology much like the Amish, they ran the entire company on paper using old style ledgers.
When they needed to send a fax they'd nip over to the (ironically) software company/IT services company next door (a deal that was struck with the judicious application of baked goods).
They where nice people to work for but it seemed very strange to running a warehouse on paper in the late 90's.
