I currently use a 2010 13 inch MacBook pro with 2.4 Core2Duo 4 gigs of Ram and 256gig HD. Looking at either a max out MacBook Air or a base rMBP. What are people opinions? I only edit tops 15 weddings, plus some seniors, families and church events. Is the display alone on the rMBP worth it? I have heard that some photos look really blurry on the rMBP, is this due to scaling issues? The software I use is Aperture 3 (hopefully 4 soon) and PS CS6. Thanks for your input.
