Even if software didn't have tremendously higher cultural barriers for usage than manual equipment, the rapidity of exchange is a very small component of the exchange value for the means of software production (which is primarily hardware anyway). The value of both hardware and software is measurable by the amount of labor needed to produce them, so it's not even comparable--it's identical.
