Hi everyone, I heard this sort of "debated" on a computer radio show, but it was more about desktops (and mostly, IBMs) - and I wondered which option is really "best" for my iBook G4. Do you "shut down" your iBook at night? Or let it naturally go to "sleep"? Do you leave it plugged in (to charge up or ?) Or do you leave it totally unattached to anything (i.e. power source, modem, etc) Any advice on what is "best" for the life of the iBook would be appreciate. I do not have any automated functions or programs that need to (or should) run at night... just FYI. Thanks and take care, Michelle & Herd
