I love the fact that when I put a bigger drive in my Powerbook all I had to do was use a free program,
Carbon Copy Cloner, to clone my old boot drive to my new boot drive and in last then one hour my new drive was an exact copy of my old drive without have to reinstall anything. In fact I put my old drive in a FireWire case and can even boot from it.
I've had my 17" Powerbook for almost two years now and have never had to restart do to a crash or had to do any maintenance at all to it, it just works.
