You might like to compare the following workflows for updating my wife's laptop (say) compared to a Win updateathon:
<hit a few keys and then ask her to reboot when she's ready or not bother mentioning it, it'll still work>
I notice your wife isn't doing the updating. She might if it was Windows.
What I'm trying to say is that to most of the population, a command-line is about as inviting as a swimming pool with a shark in it. The mistake that Linuxistas sometimes make is to dismiss this type of user as ignorant or stupid. The fact they have different life goals and interests and computers are not interesting gadgets, just the tools they're forced to use.
