I have a 2007 2.0 ghz whit macbook that i bought for my daughter. She has moved on to a new computer. Now i want to use it for my son. I am thinking about replacing the ram and upping it to 2GB. It also needs a new battery, new charger since the old one is showing wires, and I am thinking about replacing the hard drive. Total investment about 2 hrs and $300. Do you think this is worth it. All he will use it is for word, excel, and safari. should the rest of the computer hold up? I think it should. Or is the computer not woth a $300 dollar reinvestment. No matter what i am replacing the battery and the charger since those are needed I guess the question is do i replace the HDD and the RAM?
