Well, I didn't waste much time on it, but I certainly found MPSIM to be
useless because it didn't simulate the peripherals.  I am still totally
dumbfounded by my coworkers assertions of its usefulness.

I went to my boss and showed him that it only took a few wasted days to pay
for an emulator from Microchip.  Then it turned out that we already had one
that the company had gotten for free!  As near as I could figure out, it
conflicted with WinAmp or something, so the engineer who was using it gave
up on it.

True, the emulators are a bit pricey for home use, but if you're paying
somebody to write PIC code, it is really dumb not to buy them an emulator.
