Actually there are some good reasons to do it in certain cases,
especially on servers not up 24/7 (backup systems/cool standbys, fast
shutdown required, ...).  You can bring systems down or online a lot
faster.  Not everyone has/needs 24/7, or wants to pay the power bills
for running a machine that may have no users/work for over a weekend or
longer, but wants it up and running on demand.
