A good example is the good old 555 timer. A cmos 55 is 41 cents and needs a 
timing cap and resistor. A pic10f200 is 31 cents and needs no support 
components. You can also do fancy timing with the pic. I hate to say it but 
there is really no contest once you have the tools (free complier and a 
programmer for <$50). Just a shame it's killing analog skills.

Not surprising.. the cost to stock, pick, place, solder is probably the same 
for a small IC and a R or C.  So, the only possible saving would be  if the IC 
is a LOT more expensive than a single or two Rs or Cs.

There might be a power dissipation difference, or a temperature range 
difference that would push you one way or another.
