Low build cost wins-always.

Only if performance is in some relevant sense equal or better.

Insane *and* naive.

For once I am forced to agree.

Usually "the new one" outperforms the old one in some metric while
failing other parameters which may or may not matter. But the build
cost is less. That is the real deciding factor.

Tektronix and HP Agilent abandoned real oscilloscopes because the
digitizing variety were buildable mostly or entirely from comodity
parts, eliminating the electrostatically deflected high bandwidth CRT,
an item requiring skilled and nonfungible labor and hard tooling to
make. The digitizing scope also had other advantages, but it was not
satisfactory to experienced engineers and particularly not service
people. When businesses that traditionally lifted a leg and farted at
"third tier vendors" started buying analog Hameg and Iwatsu scopes
(LeCroy was importing them for awhile!) Tek invented the "digital
phosphor oscilloscope" <sic>. Now the DPO has some advantages over
real scopes and has fixed some of the flaws, but the important thing
is they jacked the price and retained the low build cost.

CD was high production cost for two or three years-as the record
company expected-but the premium price stayed high long after the CD
became cheaper than the old vinyl was to begin with, as they also
expected. They did incredibly well for a decade or so and then the
market took a dump. Now we are supposed to feel sorry for them.
Bullshit.

You get used to digital scopes though they have some annoying facets.
As for vinyl, does anybody seriously think it is better than CDs?
