Why I don't like the telephone
The following quote
from Wired explains why in a nutshell:
I couldn't help thinking it was awfully complicated to have a phone you used only for calling back - from a booth in a meadow. Why not make life easier and just put one in the house?
"What would that lead to?" another Amish man asked me. "We don't want to be the kind of people who will interrupt a conversation at home to answer a telephone. It's not just how you use the technology that concerns us. We're also concerned about what kind of person you become when you use it."
