Just found this thread and I just recently converted to a macbook from a dell so I have finally made the switch. Growing up on windows and doing photography all I know is light room and I can navigate quite well with it. I received the aperture program and I really do not like it compared to light room.... before I fully give it up and switch back to light room I wanted to see if anyone else thinks that aperture is a better product that light room and why is that?
