> Important to recognize is that while these applications can be turned off, meaning they are not loaded by the operating system or available for use, the files remain present on the hard disk in a staging area so that they can be easily turned back on again without the need to use installation media.

I hope there's a solution, first- or third-party, that wipes the staging "cache" from disk. I rather like keeping what I don't need on offline media, and, as a Mac user, I also rather like keeping down the size of my Boot Camp partition.
