Dave,

True. There is no "alert" per se, but it does give an indication as to
the nearest aircraft around me


Let's see: It's giving you a visual indication. While checking whether
that comes on, it will keep you from looking outside where the traffic
is - both traffic with an active transponder and that without one. Seems
to me that the net result is a loss of total time spent scanning for
traffic - for all of 200 bucks.

And if our intrepid pilot is not bothering to look out the window, what
makes you think that he/she will bother looking at the display on the little
TCAS box? It seems to me that adding an audable alert to that little gizmo
would be cheap...and necessary.

And yes, units with an aural warning are different in that very respect.
