When you have a computer, you ultimately have many things besides just a box that can store and process a lot of information. You have a powerful communications tool. You have a machine which can do things that you can not, while you do things that it can not (such as anything that involves actual thought). You also have a certain type of responsibility which borders on actually having a full fledged hobby, whether you really want to or not. A computer is a lot of responsibility, rather like having a pet. Of course, the simile breaks down a little bit, when you consider that this is a pet that can not move on its own, and can do all kinds of tricks that very few people really understand (rather like having a magical lizard that can teleport around the room, or a fish that can grow to be a mile long).
Of course, the relationship between computer owner and computer is a complicated one. Not so much because you have a lot of different files to keep track of, or because you have to manage your schedule carefully to make sure that everything gets done (in spite of all the attractive temptations that exist on a computer). You have also got to update on a regular basis, whether you like it or not. See, computer software is frequently released without being completely done. Except in the case of recognizing new online threats, which will probably never be done. At any rate, updates are a good idea.
What a lot of people do not realize about updating is that you might not want to update every time a new patch becomes available. When you really think about it, do you really want to be the guinea pig that the designers of the software end up using to figure out whether the patch ends up doing more good than harm? Inevitably, you are going to face issues of that nature, because a lot of times the software itself is going to need a lot of patches before it really works properly.
