With nine fans in the tower model, I got to assume the machine
produces a little heat, so it may be awhile before the G5 makes it to
the laptop scene. Most people keep their Mac for five years. I
think you are safe on the software side. On the hardware side,
machines always get faster.
Perhaps you could look around and see if IBM is producing a low power
model of the G5.
I have a Mac 170 Powerbook. I'm having intermittent problems with the
hard drive. Previously it would not recognize the hard disk. After not
touching it for a while it miraculously fixed itself, or so it seemed.
It now will only get half way through booting up, and hangs when I try
to boot off a startup disk. Is there a 'safe' boot up mode for
troubleshooting? I know little about Mac OS so I anyone can forward some
documentation on it I would be grateful.
