The part where the condition of a frame 20-30-40-50 years from now is presented as if it's somehow a valid issue in the "frame wars". Its a bogus arguement, because the frame is long beyond its intended lifetime by then. A bike is a tool - a cheap tool - not a lifetime investment. If a tool is useful in 40 years, that's great. However, you expect to buy a better one in the future anyway so it doesn't matter.

I am not saying anything about people who CHOOSE to build up old frames that happen to suit their fancy, because I am one of them.
