Well, it's not of course.  What you do when you move depends on what is available at that time and options are likely to improve as Science Marches Forward.

I also think when to move depends on what you're trying to do. The protection you need for online ecommerce buying razor blades is very different from launching missles is very different from long-term archival storage of official documents.

I think both of these things should at least be touched on.
