So, that happened. I was planning on buying the new MacBook pro until the price came out and I realised I'd have to sell a kidney. Now I'm looking at trading up from my mid-2012 15" MacBook Pro Retina. The 13" pro that came out last year seems like the one to go with but I'm a little worried having compared the specs. Am I right in thinking the 13" 2015 MacBook Pro Retina might be a step down from the 15" mid-2012 MacBook Pro Retina in terms of performance? Has anyone got any real world experience?
