Hello, I have ordered a 13 inch 2.7GHz/512GB/16GB touchbar MacBook Pro, but am now getting some doubts about that touchbar. As a Maths/Computer Science student i do not think that I can make great use of that gimmicky bar (if not the contrary); I'd rather have the function keys. However, the better processor and faster Ram made me buy the touch-bar one. How big will the CPU/GPU advantage of the above MBP be on a 2.0GHz/256GB/16GB non-touchbar MBP in the scenario of light/scientific coding and regular Uni-stuff? In light of the battery-size reduction I am now additionally concerned about battery life. Will the 15Watt Processor of the non-touchbar MBP in addition to the slightly bigger battery yield noticeably better battery life? Will I feel ripped off when not going for the touch-bar one, as prices differ only slightly and specs seem much better? Thanks in advance.
