I'm working on a project that will need a couple of inputs and around 16
outputs.  The outputs will change at a few hertz at the fastest.  Is it a
better design to use an 8-pin PIC and send the outputs serially to a couple
of shift registers or a 28 pin PIC and use the outputs directly.

It seems like the shift register solution is better design because it just
feels wrong to waste so many IO pins on something that simple, but the
larger pic means less components, less soldering,  and simpler software.
