If you believe that I have a bridge over the East River for you to
consider purchasing.

Under some conditions a cable-delivered digital signal might look better
than an analog one, but only if the cable system has real problems.

There are some situations where a cable system can deliver a usable
analog signal but the QAM ones are unwatchable.

But the main reason cable systems are moving to digital is simple: They
can shoehorn more channels on the wire.
