Next year I am going to highschool, and need a new computer that will last me all 4 years. I want to get the macbook, 2.0, unibody one. I was going to get one new, but I saw the refurbished prices. I am a little worried because I was looking on the forums and saw a picture of one that had scrapes on the bottom of it. I have enought for the refurbished one right now, but should I save up some more and get it new? I'm really afraid its not going to be what I am hoping for. What have been your expirences buying refurbished?
