I do go without cable. I also go without a home phone line. I have dry DSL, I pay less than $50 a month for a great high speed connection and no filtering of my traffic.
I will never get rid of the internet, no matter what. I will never live in a place that does not have a high speed connection. It is simply an awesome tool that I use everyday, not only for my job and entertainment, but to learn all sorts of things, and also to facilitate living my life.
As for what else I would get rid of, I already live a modest life. I rarely purchase things that are not food or raw materials (fabric), and I often use my skills to increase my income (web design, selling things I sew) or reduce my outgoing costs (recycling, reusing, veggie gardens). I am in fact heading over today to my parents home to clean up the garden in preparation for this year’s vegetable planting. That’s one thing I would advise anyone to do who has space, do a bit of research and plant even just one veggie this year and help it grow.
