I have MBP 2017 13" base model. I require a slightly bigger screen so I am thinking about buying MBP 2018 15". Touch bar is kind of a huge turn off for me. I really don't want to use any of its features. I just want the F keys which I can use to increase/decrease brightness, volume etc. just like I do on my current MBP. Can I just use the touch bar as regular F keys and pretend its not a touch bar with all those fancy functions and features?
