Can someone give me the Reader's Digest version tutorial on ignition?  I
understand how the spark is generated (v=l*di/dt right?) and I understand
timing and that it changes under load.  

What I don't have a feel for are the hidden workings of the distributor.
The well-named vacuum advance feature seems obvious but I have heard of
weights in the distributor whos function escapes me.  

Usually I am willing to suspend logical thinking and beleive in magic (as
in the case of SU carburetors :-)) but in this case I'd like to know more.
What about electronic ignition - which components are replaced - in
what ways is it better, etc.  

I've seen some posts about Pertronix and Ignitor (brands) and seem to
remember them being characterized as easy to install and less than $100.
Gee, points are only $2.50.  (I'm embarrased to say I want something and
don't know why!)

Oh, and one more thing:  Could you compose an essay espousing the virtues
of electronic ignition?  It should begin like this: "Dear Lonnie, your
husband simply must receive a (Pertronix/Ignitor) electronic ignition
system for Christmas because......."

Thanks!
