An old G4 powerbook to be exact. I am just looking for one for my 8 year old daughter who wants to do learning games, iLife things and KidPix so I am thinking I am going to need more than 256 RAM and a 10 G hard drive, but I am thinking if I can add it later, that would be fine (f the price is right). How much RAM can an old G4 handle? Also, are there any problems with that model I should worry about (it IS titanium, but it usually won't be used as a portable machine). Also, how slow is 400GHz?
