Hello, guys. This is my first post here. I know it's a tough question to assert properly, but I'm looking for opinions from Macbook Pro Retina users who switched from a first generation model to the current generation. I have a 15'' MBr that I bought right after Apple launched it, in mid-2012. Has anyone in this situation thinking of getting the mid-2014? Thanks for any input/opinion. Rebêlo.
