I have had my MacII vertically mounted in the Kensington Stand (with
extension cords) for over a month.   It gets pretty heavy usage and
there appers to be no problem.  Certainly there are no signs of
overheating.

My Apple friends were surprised to hear that the manual says you
shouldn't do it.  They were equally surprised to hear that the manual
states that the life of the hard disk is prolonged if the machine is
turned off when not in use -- nobody at apple ever turns off their
machines, they said.

Conclusions.

1. There might be someone at Apple who actually knows the answer, but
most of the ones there that we are apt to talk with don't know any
more than we do -- they are users of the hardware too, even if they
wrote the software.

2 No obvious difficulties.  Of course if my machine does
fail, one will never know whether the vertical mounting was
responsible.

3.  All this strengthens the well known finding that few people read
manuals, even at the place where they were written.
