So, I am on a MBPr 2.3 base model with 8GB. I am really thinking if I should go for 2.6/16gb version because of some limitations in PS CS6. My question is for people who upgrade every year. How big of a hit in terms of Resale value (depreciation) should I expect to see if: 1. I sell my 2.3/8GB base model next year 2. I sell my 2.6/16GB model next year Of course for a question like this, there is no right or wrong answer. But I wanted to ask from people who like to upgrade yearly based on their previous experiences. I would appreciate any help. Thank You.
