Thanks! I might again check at an Apple Store to see how much heavier and thicker the cMBP is and how good the screen is. I know the facts, but i don't like to start a lot just based on facts.
So either i will buy 15" rMBP or cMBP.
And if i choose cMBP, should i buy extra RAM myself or already configure it at the Apple Store? It would get cheaper if i do it though.
