I disagree with this. Are you actually saying that a powerbook shouldn't be used for extended periods of time? I use my TiBook easily 12 hours a day, and have no problems whatsoever.
No, I am not saying a powerbook shouldn't be used for extended periods of time.
I am not saying I have problems using my iBook 12 hours a day.
I am saying that when I am NOT using it for 12 hours I find it better to turn it off than to put it to sleep.
if using a battery, you can deplete their battery faster, etc.Well yeah, using the battery uses the battery. No way around that as far as I know. :)
ok... so, once again I should have spelled out everything. _If_ the battery is in the computer, _and_ the computer is powered by electricity, _then_ the battery life can shorten considerably. While newer batteries are not supposed to suffer from memory effect, I have experienced first hand where a battery was left in the computer that was always powered on by electricity... eventually the battery life became less than half an hour. This is because the computer is powered by the battery, which gets drained on use. The battery is being charged by the electric current, which charges the battery almost as it is being drained... so the battery is never drained almost completely, etc. Again, I know the new batteries are not supposed to suffer from this, but I don't believe the hype... a new battery is upward of $100, and I just don't want to find out the wrong way. I save my battery for when I am actually travelling with the iBook. At home, it is always powered by electricity.
several reasons...

Besides, what a waste of electricity. If I am not going to use the computer for 12 hours, why have it on.
Why not put it to sleep? That's one of the best things about OS X, IMO. Sleep and wake are almost instantaneous. It's much faster than waiting around for the thing to boot up every time you want to use it.
- putting a computer to sleep still consumes power.
- the computer seems to lose its tcp settings on wake... this was a known problem in OS 9, and I have personally experienced it in OS X... I wake up the computer and it doesn't know how to get out to the internet via my switch to DHCP-ed cable mode to the outside world. I have to log into the switch, release the ip address, and have the cable modem get a new lease.
- I may still want to turn off the computer.
The point is --
if you don't ever turn off the computer then psync with crontab will be a good solution. anacron is only a partial solution because it doesn't handle time diffs of less than a day.
if you do turn off the computer, then either remember to run psync before turning it off, or figure out how to have it run automatically on shutdown.
anyway, that last para above was the message. The rest is... I dunno... noise maybe.
