However, the one thing they fear more than their own computers is a change of any kind in their own computers. If I were to sit down in front of a Sun workstation running SPARC or something, I could probably navigate around and get some things done, even though I've never used that OS before. A lifelong PC user from the reception pool may not know shit about Windows, but at least s/he is somewhat familiar with how a few things work. I tried to teach my dad how to navigate the Linux filesystem, and it was like trying to teach a dog how to read. He knows his way around the Windows filesystem (sorta), but only through 15 years of repitition. Point - secretaries would notice the difference, and be upset by it.
