Hello to all. I need to upgrade my old white macbook and have been waiting for the mini to update. I mainly use my computer for web surfing, iTunes, photo editing with iPhoto and home movie editing and converting using iMovie. My macbook is intel 2.4GHz core 2 duo with 4 GB ram. I am thinking of the stock middle model at $699. Is this mini good enough? If not, recommendations are welcomed. Thanks in advance!
