Yes, and if you acquire multiple machines to handle one computing load, you get an added bonus - EDUCATION, as follows: You can find out how networks work, and how they fail. You can discover that you have to balance your user load across machines, and that the load will invariably change faster than you can adapt. When you start to do file backup, you'll discover that either you need tape drives on every machine or you get to learn about file system backup across the network. And if users don't have most of the files they need for their work on their home machine, the network overhead will eat you alive. (I think I want a statement of Grosch's law here??? My memory fails me.) I'm not flaming about the idea of "a computer on every desktop" - I think that's a good idea - but WATCH OUT. If you've got lots of little jobs going on, fine - but if you really have a community of people trying to work on one large project, you may be going the wrong way. (Using nine little computers to do the job of one big one can be like trying to have nine women produce a baby in one month.) -- "A friend of the devil is a friend of mine."
