I'm in the manufacturing sector, on the integration side of things now, but yes, change is always a battle. The way I see it, the problem is two-fold:
Side 1: the workers, especially the labor portion, are extremely resistant to learning new ways to do things unless you can prove, beyond the shadow of doubt, that the new way will be easier than the old way (aka, less to remember/think about) but also does not diminish the quality of their work or increase the perception that their coworkers might see them as having it easier than them.
Side 2: the people responsible for purchasing and resource allocation often do not know what they are buying. In any shop, if you say "we need new PC's for the office" the first thing the purchaser will do is ask a supplier for a deal on a fleet of Dells because that's just what they've always done. If the company is larger and has an actual IT department, they will just provide Windows PCs because that's what they were trained to support. The alternative, Linux, is never considered because they simply don't know anything about it and it's not being offered by their suppliers anyway, so why learn?
