Partly it is an expense. In some places (like California), electricity
is very expensive. Having a 100+ watt machine on all the time adds up.
You also are pumping heat into the room, which you may be paying again
to extract with your air conditioning.
Aside from any cost constraints, there's the environmental aspect:
you're using energy that you don't need to use, and it probably comes
from burning fossil fuel. If it's not a big hassle, just stop doing
it. Like turning off the lights when you leave a room or the heater/ac
when you're not at home.
You have a point about powering the box on and off being harder on the
components than just leaving it on all the time. If you are doing a
bunch of recording during each day, then it probably is best to just
leave the machine on. In my case I'll often go > 24 hours between
recordings, sometimes several days. Not much of a reason to leave the
machine on when it is busy a few % of the time. The components of the
system are designed to deal with some power cycling. Typically new
components either fail quickly or they last. Usually you'll be able to
get them replaced under warranty when they puke. Aside from a rash of
bad hard drives (replaced under warranty, run in a 24x7 box), I almost
never have had a component die before it is retired during an upgrade.
Interesting OT research topic: where is the line between leaving the
machine on all the time and power cycling? It seems like there's a
point where the wear from being on without being used much is more
than the wear from startup for those occasional uses would be. Can
anybody point to data?

I think you may have me confused with someone else, I've never used
WOL.
All my boxes are just on 24x7.
Often wondered about why people are so concerned about WOL
for a myth box. Where is Electricity so expensive that leaving it
on 24/7 is a problem?
If you turn off the monitor you kill off 80% of the electricity usage
anyway.
I've metered boxes doing nothing. They draw squat.
Its harder on the machine being powered on and off all the time than
it is to just leave it on.
I have setup nvram-wakeup with the current fedora, if people are
interested I can post my working configuration information here, or I
can see if Jarod would take my notes and add it to his tips and tricks
section of the mythtv fedora how-to.
