I don't believe that the fuse bits are simulated much, or at all.
So you could burn a chip with the fuses wrong and have it not work
at all.  Likewise, I doubt whether the simulated clock 'drifts' as
much as the internally generated clock, so you could get timing
problems as well.  And of course mplab simulation is much slower
than realtime, so it's pretty useless at detecting problems that
might be timing dependent.
