Decided that waiting until summer and crossing my fingers for a Skylake MBP is too long. I have a 17" 2009 MBP that still has a HDD and 4GB RAM, but I'm still in my first year of college so I definitely need something more portable and with more battery endurance. I've decided that a 15" Retina (at almost half the weight of what I previously carried) was what I wanted and I narrowed it down to two refurbished models, a $1489 8GB RAM 2013 and a $1699 16GB RAM 2014. They're basically identical (256GB SSD and like 0.2GHz difference) except for the RAM. I want this laptop to last as long as my 2009 did or even longer, so I'm wondering if the extra 8GB of RAM will be worth it in the long run. I'm studying Computer Science right now and I'm anticipating a lot of compiling (I'm not sure how much power that takes) and probably iOS or web development down the road. Should I spring for it? EDIT: Shoot, I forgot to say RAM in the thread title.
