Alright, so I picked up my refurb 15" rMBP early 2013 base model last week. Everything about it is perfectly fine for now. However, I've been thinking a lot about the inability to upgrade this thing going forward and I'm considering returning it and swapping it out for the top-end current "late-2013" rMBP. With the education pricing I'll get on the new one, it would be an additional $780 out-of-pocket. When I bought it, I considered this an unnecessary expense. Now I'm thinking it isn't so bad since I'd be looking at $500+ just to upgrade the hard drive in a year or two. Also, as I'm sure I don't have to point out, I'd be getting a lot more for that additional $780 than just extra SSD space. Double the SSD space, double the RAM, double the video RAM on a better dGPU, better integrated graphics, a newer CPU with +2MB on the L3 cache, and PCIe based memory... I don't know. Any opinions? The other way to go would be to just hold off, sell this machine in 2-3 years and buy whatever awesome new computer Apple is selling by then.
