I tried to cut out alot.. probably should have cut out more :-) WHAT IS AN AVERAGE USER ??????? A GAMER ??? A PROGRAMMER???? A PERSON WHO USES THIER COMPUTER FOR BUSINESS REASONS??? AVERGE TO WHO ?????? in another posting someone said average users don't call bbs's, and dont own modems.. SORRY.. why are there more BBS's now than ever, more "POWER" users no... more "average" people with more computers.... > >The "average user" would be satisfied with a desk accessory, while the >"power user" will want multi-tasking.

(Which is why I think >the "power user" should own a Sun or Apollo or VAX workstation and >forget the piddling PC market). Do you also feel anyone who wants to drive fast should own a ferrari or lambroghini ????? even if they can't afford it??? but instead maybe just put high test gas in the old chevy chevette ?????? I FEEL ONE QUOTE SAYS IT ALL..... "The most important concept in modern operating systems is undoubtably multiprogramming. By having a number of programs in memory at the same time, the cpu may be shared among them. This scheme improves the overall efficiency of the computer system by getting more work done in less time " ---from Operating System Concepts, Peterson and Silberschatz for more, read chapter 4 of the above book.... When we had older computers, we always wanted more power, and more cpu cycles to get our work done faster. Now we have greater speed, speed that very often gets wasted because of I/O, and waiting for user input, and so on. With multitasking, the cpu is used more efficiently, and we can of course get more work done. Period. If I want I can constantly have a CPU intensive ray tracing program running, when I want my editor to run, and keep the ray tracing going, but give more cycles to the editor, I can do it, as easy as I just said it, then when my editing is done, go back and raise the priority on the ray tracer. if I couldn't do this, when my ray tracer was working, I might as well forget about my machine, and not use it for 12 to 40 hours as it completes the picture. > >Now, for the "Why I don't want a multi-tasking system".

Do you cook the steak, then eat it, and cook the corn, and then eat it, then cook the potatoe, then eat it,then make the salad and eat it, etc. ect. etc..... ????? NO, You Cook everything at once, except of course the salad, I hate cooked salad :-), and then eat everything at once... That is NOT linear, humans are DEFINITELY not linear. The classic about walking and chewing gum, is a perfect example.... :-) > >(yes, I know I'm cross-posting this ... some of my best friends own > Amigas, Macintoshes, IBM machines and Atari STs.

Well, just remember, the vaxstation is at work, but my AMIGAstation is at my home, right where I get MOST of my work done.... mike Disclaimer : OF course they are my ideas, who else would have them ....??
