Hey guys, I'm currently deciding between the mid-range 13 inch Macbook Pro Retina (for 1,600) and low end 15 inch Macbook pro retina (for 2,000), and I was wondering if a computer's overall power has anything to do with its expected reliability? I've been searching around online for a while and can't seem to find a definitive answer. First and foremost, I'm looking for a laptop that will likely last as long as possible (hopefully, at least 5-6 years). The 15 inch is honestly, more power than I probably need (mostly just take class notes, do research, video streaming, VERY light gaming, and occasional Photoshop). But my computer is being subsidized through my college (up to $1,600) so I'm willing to pay an extra $400 if that would mean its more likely to last me until the end of law school (I'm a junior in undergrad now). So, if I shelled out a bit extra for a computer capable of more than I use it for, does that generally lead to a longer overall lifespan? Any opinions would be helpful, thanks.
