Hmmm... I can't recall when the marginal cost of even large software
products, in terms of media, was anywhere near $100.00, but software
is routinely sold for far more. Some of this is the cost of support
services --- but then again, it isn't hard to find software packages
distributed over the net for four-figure sums for which support will
set you back even more.
I suppose one could argue that the market simply hasn't had time to
equilibrate...
