Well, a PIC chip can be a more compact solution, and when engineering time is more expensive than component costs (i.e. prototype), it works quite well. Just get a PIC that has an internal oscillator and you've gotten lots of stuff like comparitors and timers all inside the 8-pin DIP. I just think more in terms of SW solutions than HW discrete because of my background.
