Hi all, Been using 2014 rMBP 13'' and love it, but I want to give it to my fiancee to use. I need either 2015 rMBP or 2016 because I want to drive a 4k external monitor at 60hz. I got a 2015 refurbished rMBP but the keys feel a bit mushy compared to the 2014. I'm going to Apple Store tomorrow and will either get the keyboard fixed (if they admit it's an issue) or return it for a 2016 (want to play with the keyboard and see how I like it). I can't decide between the two 2016 13'' models. Would appreciate if someone can help answer some questions. The non-tb has slightly better battery life than 2015 and tb models right? How do they compare? I can't find any actual tests. Battery life is fairly important to me. I hear people complaining about battery life on some units. Is that moreso with the tb or non-tb? In terms of performance, the 2014/2015 is fine for my purposes. I'll mainly be using it in a healthcare practice so lots of typing and lots of tabs open (considering 16gb to future proof but 8gb will probably be fine). Any actual difference in performance between TB and nTB in day to day? Looking at gpu, iris 540 (non tb) vs 550 (tb) vs 6100 (2015) - is there any difference in terms of UI lag or powering external display? That's my only concern with GPU. Not doing any gaming on this.
