Yes I have, and it is wonderful. We're so connected all the time that it's nice to be unavailable every once in a while. Sometimes I don't want to be reached. Of course, It would be a great inconvenience to go without a cell phone all the time, but it wouldn't be impossible.

I spent three weeks in Europe with no cell phone before I got one. Those were some amazing days. I forgot that I ever had a cell phone. I was always too absorbed by everything that was right in front of me to think about calling anyone. Except when I was looking at the Holy Grail in Valencia. It would have been cool to call someone and brag about it. ;-)
