I was thinking the same thing, Boris. It's probably easier and cheaper not to have to change the production, since a lot of production costs are "start up" costs, are they not? I heard something to that effect when people were wondering why not convert some of the struggling auto factories to make say solar panels, and the response was basically it would be cheaper to build an entire new factory than to convert. So, I just assumed the same would be true on a smaller scale - changes are more expensive than getting it set up and sticking to it.
