I am torn between getting a Retina MacBook Pro and a 13 inch MacBook Air. I want the power of a rMBP for possible video and audio editing. It's mostly probably going to be used for web surfing and writing a book. I do create a little bit of music in garage band but nothing really substantial. Is it better to have the power and not need it? I also love the wicked battery life on the Air and the lightness of it, so the idea of carrying a brick does not appeal to me. What say you? Which would you do? An Air or rMBP, of course I think I will wait to see if they refresh the line in June. Please advise community!
