Hi, I am confused between the two 15' models. I am getting them at the same price ($1799). Mid 2015 has a slightly larger battery and force touch trackpad. Mid 2014 has faster processor, twice the storage, NVIDIA graphics card but no force touch. I was thinking of going with Mid 2014 as I am getting it for the same price with much better configuration. What do you guys think? I will be missing out on ForceTouch trackpad though .. Mid 2015 Mid 2014 Thank You.
