You're right Frank, it seems like there is only a few differences, either 160 or 250 on the hard drive, 1 or 2mb on memory and the battery size. Since this is for 13 year old, I don't want to put too much into it. She has access to a desktop at her mom's and my Apple laptop at my house. She will be tickled to get this so that she doesn't have to fight with her little sister for computer access. If she had her choice she would ask for a MacBook Air, but that's not happening, at least not this year or next year or the year after that. Too much money for her to walk off and leave somewhere.
