Cell phones are fine for calling a known number.  OR receiving and send
faxes  OR receiving incoming calls from various sources not all of whom you
may wish to speak with at the time.  As such they are "defined point to
point communications links".  A CB is broadcast, sent to anyone who may be
listening on that channel at the time.  Nice for asking for assistance
locally, finding out otherwise unavailable information regarding road
conditions, availability of necessaries such as showers, food, inexpensive
fuel.  Also fine for chatty stuff with others of various social strata who
also have a CB. Good for impromptu language lessons, listening to life on
the road, soliciting companionship, asking WTF the traffic has been backed
up for seventy miles east of Moose WY, and learning that the road is
CLOSED/CERRADO/FERME due to fire.

YMMV and transmission distance will vary. FWIW I have for sale a CB with
controls all on the microphone/handset.
