Keep in mind, folks, that some of us remember when there simply weren't computers which we could use. Back when I was a boy, even the US GOV couldn't afford a computer capable of what my smallest simplest Windows9x system is capable. The fact that I don't use it for pure number-crunching is a recognition that there are other things equally deserving of the benefits of advancing technology. If a picture is worth a thousand words, then why type them if it's easier to draw the graphic representation. Moreover, if you have to read my 1000 words (about a page) and then draw yourself a graphic representation to understand and digest it anyway, why not stick to the graphic? A simple graphic can save both ends of a communication time, effort, and embarassment from when there's a miscommunication.
