This brings up an interesting point.  I have heard several (actually more
than several) complaints about hardware problems in the mid to upper level
PIC devices.  I even had someone tell me they were going to stop designing
with Microchip parts because of the hardware errors.

Now I know how easy it would be every time a program isn't operating
properly to blame the hardware, but I am getting the impression there are
actually a few problems other than the "baud rate generator=1" problem he
mentioned above.  Has anyone been keeping a list of the problems so we don't
all learn the hard way?  I know there have been revisions to some of the
chips (xxxA), but I understand even the revisions aren't quite perfect.

Can someone spread some light on the matter?  Hopefully I'm way off base here.
