Hi, I need to purchase a 15" rMBP and I need some advice from MBP users here. I decided to purchase my first macbook pro and i will go for the 15" rMBP. I have few more questions. My main uses are photo editing works with photoshop & Lightroom. I'm a photography Enthusiast & i dont earn money with it. I'm a IT consultant by profession so spend lot of time with computers.All these years I have been a windows pc user. Here are my questions. 1. Do you think the lesser config of 15" rMBP 2.0GHZ quad core, 8GB RAM, 256GB would be good enough for my photoshop & LR works or do you recommend to get the 15" rMBP 2.6 GHZ quad core, 16GB & 512GB storage model ? I'm just trying to save money at the same time this is my first purchase so i wanted to choose a good one ? 2. Has anyone have any experience buying an refurbished 15" rMBP directly from apple? If i buy an refurbished there are some good savings upto $400? Do you recommend buying a refurbished vs new? 3. I have some student friends. Do you think buying a new 15" rMBP with apple education discounts would be cheaper or same price as refurbished ones from apple? If its coming to the same price I can get a new one. 4. I also need to get the applecare. I do see it costs $349 from apple whereas it costs $244 from B&H. Can i get the applecare separately from B&H and add it to my rMBP which i get it from apple ? Thanks in advance for your time. I appreciate your help to clarify my questions.
