But is the Pro better if I gerne 16 gb RAM? Excepti from the light in the screen 400 vs 500 nits
It has bit bigger batteri, a bit better microphone, a bit better speakers, touchbar and a bigger power-adapter in the box.
For me the missing fan in air is an advantage. I love the complete silence and in daily use there is no speed difference and what it have seen of difference in longer tasks is minor. I have Bought thermal-pads, so I could make contact to buttom-plate. But it really feels unnessary.
I am tempted by the touch-bar, never tried it, but people have mixed feelings about it and rumors says it will be gone with next Macbook Pro revision.
The power adapter you can buy separately and take advantage of. I did. I had planned to to have two power adapters anyway, but it also turned out, that the usb-hub I bought required more than the 30W from the included power adapter to enable powerthrough (charge through the hub).
I would like the brighter screen, but only because I know there is a difference and I then tried to sit in the sun. I am sure the hardware is the same and it is just limited by Apple. If you are not sitting in direct sun with sunglasses, the screen is plenty bright and I am not sure if 500nits is even bright enough in the sun with sunglasses.
Speakers and microphone are plenty fine for me. Hardly ever use them anyway.
All in all, the price was the same and the fan really really cannot be heard, I would likely choose Pro. But none of the extras is important enough for me, to pay the difference. Also I am comming from an 11" Air, which has been solid and I like the wedge-shape.
