Software doesn’t have wear and tear. There will never be a need to replace it.

Which is why we're all using Windows 3.1 these days.

A poor analogy to the AutoCAD software question.

Some of the older versions (Ver 12 in particular) are considerably better drafting engines than the current versions. The recent versions are, to put it rudely, a pain in the ass to work with for most users, which has caused demand for the easier to use older versions to climb.

If your comparison to Windows were valid, the stuff wouldn’t sell at all.
