Moving coil meters are still useful for 'peaking'.

Moving coil meters are much nicer to use than digital. They might not be quite as accurate or as sensitive but they do everything that we want most of the time.

I also find that DMM's encourage over analysis where it isn't needed. Actually the high impedance of DMM's often results in erroneous results which wouldn't happen with a 20 KΩ/Volt analogue meter.
