Ok, so I can either get the base 13 inch retina Macbook Pro for £999. It has a 2.7GHz Intel core i5, 8gb ram and 128gb flash drive. Or I can get the 2012 model Macbook Pro, which has a 2.5GHz Intel core i5, 8gb ram (upgrade) and a 500gb HDD. Should I go for the nicer design, higher battery life and better display? Or the higher storage space? I'll be dual booting with windows, and doing some game development in C#.
