The PCs are faster and better. Faster and better. very interesting statement. My car is faster and better than the space shuttle in the same way you are comparing PC's and mainframes. I would NEVER use the space shuttle to go to the corner grocery, but i would use my car, and I would never use my car to go to the moon, but I might consider the shuttle. In the same light: I would never use a PC to predict tomorrow's weather, but i would use a cray, and I would use my PC to handle my store's accounts, but not a cyber. >The PC revolution, like our free-market system as opposed to communism, takes interesting analogy -- Functionality, Efficiency, Luxury. isis!dragheb | dragheb@isis.cs.du.edu
