I have a white 2007 Macbook with 2.0GHz Core 2 Duo and 2GB of RAM. My hard drive is the original 80GB that came with the machine. I don't have much on it but was wondering what you thought if I replaced it with a 120GB SSD. I am getting tired of seeing the beach ball and I am just using the laptop mainly for email, internet browsing and some pictures. Have you done it? If so, was it worthwhile? The machine is ok but I would rather not purchase a new MBP yet. The $200 for a good SSD seems tempting.
