I decided that I should get a new mac. I currently have a early 2007 white macbook. I am a high school student and I will be using this for browsing the web, watching tons of movies, and homework with word. I really don't know if I need a new laptop but the macbook I have right now is out of memory because of torrents and the colors look washed out. I don't want to waste too much money but I want to get the best laptop that will last me for a while and that I will satisfy my needs. Any help would be appreciated.
