- I agree. Even if I were to stop doing "number crunching" on my workstation,
- I still care about how quickly it can pop up the mailtool, or pop up a
- new window, or run a document thru LaTeX or compile a program. Once it can
- do any of these (or similar) functions in "zero" time (which could be defined
- as less than .25 seconds) then anything faster wouldn't affect me. For now,
- SS1 speeds are fair, but not great. I have an SS2 (40mhz) with a local 400
- meg disk and it is better. However, as X grows and increases it's function-
- ality more, it will become too slow. My old Sun 3/50 seemed quite fast
- five years ago. Now, you can't give 'em away. In essence, any appreciable
- delay is noticable and anything that can be done to reduce it will have a
- BIG market. When you start cracking .1 sec intervals, then you really are
- talking to the true number crunchers and not the majority of workstation
- users. But there are still Cray's for 'em ........
