I agree with that.  It's usually better to use a larger PIC than to
externally multiplex pin functions.  I've used 64 and 80 pin PICs in various
projects as appropriate.

However what I was saying is that the overwhelming majority of my quick
one-off PIC projects can be handled with a 28 pin PIC without any external
multiplexing.  If I used a 40 pin PIC, the extra pins would just remain
unconnected.
