Once someone has a package loaded in their network, they need a very good reason to even consider a different package. "don't fix what isn't broke", but managers often have no idea if something is broke or not until it completely stops.
People forget how fluid technology is. Just because a package is great today doesn't mean it will still be "the package" in a few years.

Who knows what tomorrow will bring?
