I think we would see a lot of software, clothes, wood and furniture sold on craigs list. I think the country would look like items for sale in the college post office.
We would just reuse a lot stuff. computers would have reusable cases and power supplies and only the cpu board would change. goods that are elastic would be consumed less as if the price had increased 30%.
Doesn't sound too bad to me....cut down on landfills, not to mention all the dangerous chemicals that are leaked from the PCBs of discarded PC's.
