My g/f's computer was damaged beyond all repair last week (one year or so old Compaq laptop) so I've been searching around to get a deal on a new (used) one. Previous to the Compaq she had an ibook which she loved. I'm also a big fan of Macs (plan to switch when my Toshiba gives up the ghost) but am not too sure about the older ones. I'm looking for something in the $500.00 range (or less) or so on Ebay. Her needs are very basic: web surfing, music storage with itunes, light photo editing, etc. Just for the sake of longevity, I would like to find one with one of the newer operating systems (OSX I think???) so what specs do I need to run that without it slowing down too much. Were there certain models that were better than others? I'm looking at the smaller screen sizes......12-13" or so.
