I have never owned a Mac before so I am really new to them. I am considering going form the PC world to Mac and just wanted some suggestions. I will be editing photos, video on a personal basis. Nothing heavy duty just personal stuff for fun. I realize both machines may be over kill but I hate buying down and then need more speed in a year or so as I have experienced with PCs. Any other suggestions, and will the iMacs do everything I am looking for? They seem to be pretty fast and powerful.
