Sometimes there are advantages in opting to use the old way.

For instance, a mains transformer based power supply, normally has a
far longer life than a switched mode power supply, although the latter
offer the advantage of supplying far higher currents at lower DC
voltages. Still, for an old electronics engineer, provided a 3 phase
power supply is available, very high DC current outputs are possible
with a ripple of only 15% of peak voltage. This performance can be
achieved even without a smoothing capacitor! [For those who want the
exact percentage, it is a matter of solving an equation containing a
couple of sines. Draw 3 sine waves with the same amplitude but reflect
the negative have cycles into the x-axis. Then solve for the
intersection points.]

So, the musty fusty old ways cannot be completely forgotten. In this
case, if you want very long term reliability you have to use the old
way.

My little motto is: use the best fitting technology available without
giving undue consideration to whether its old or new.
