I don't plan to present arguments that address previous postings in detail,
because it seems the point has shifted. The ridiculous claim in the ad is
that the UNIX PC has 75% of the power of a DEC VAX 11/780.
If this is true, I should be able to replace 3 VAX 11/780 with 4 UNIX PCs
(and support the 100 - 120 users on the Vaxen).
To claim such a replacement ratio, as the ad does, is clearly dishonest.
A more realistic, but still rather absurd, replacement would be to replace
a VAX 11/780 with 13 UNIX PCs, assuming that each UNIX PC will support 3
users as Ms. Vincent states. This would cost 115% of an VAX 11/780 if
the "7% of a VAX" cost statement is correct.
AT&T should be fair and honest in its claims. They haven't been.
The AT&T ad is a good example of taking an irrelevant measure of raw
processor speed and building a lie from it.
