I recently read that it is a good idea to let a new Mac (G5, at least) run for awhile before doing anything to it (i.e. installing anything, etc.), as this may prevent future problems down the road. Is there any validity to this? I know that computers are not cars, but intuitively it seems like a kind of "break in period" might make sense. I am not technologically knowledgeable enough to have any idea about this, so hopefully someone more inclined can enlighten me.
