Hi, I'm new to this forum but I've been browsing various threads for awhile. It's finally time for my 6yr old HP computer to retire and I'm looking at getting a MacBook Pro. The problem is I'm having a tough time deciding between the 15" MBP normal and the 15" MBP retina. A little background....I'm finishing up my undergraduate degree and moving on to medical school. I need a computer that will last at least 5 years, (hopefully longer). I want something fast that will be able to handle various applications running at once. I don't do gaming, but I am into photography and edit a lot of photos. Money isn't really a major factor, but I would like to keep it under $2500. I noticed that the base specs for the rMBP make it cheaper than if you put the same options into the normal Pro, (8gb memory and 256gb solid state/flash is $1,999 for the rMBP and $2239 for the MBP). If I want whatever computer I get to last a long time, what are some specs I should definitely look at having, (memory, storage, etc.)? Any overall advice?
