Agreed...but I wonder if there might not be a better solution than
building unserviceable devices, which wind up jamming our landfills!
One thought...I have a c. 1970 Sony TV which has a number of replaceable
plug-in modules (probably all long since out of production by now).
If our devices were built this way...and if there was any standardization
of modules like there was with tubes...things could be repaired rather
than discarded...
