I have used my Macbook for the past few months and have been won over to the Mac side. It is true. Once you go Mac, you never go back. Now, I am considering purchasing a new iMac. My only question is do I need 2 gb of ram? I mainly use my computer for internet searching, e-mail, word processing, downloading and listening to music, watching videos and dvd's. I would like to do some video editing with iMovie. Other than that, I am not into video games or anything like that. So, any suggestions?
