Maybe a large part of why hardware buttons work so much better than software buttons is that they just are there. They do not pop up whenever you enter a new screen, and usually, you can't miss them (as in 'oh, I didn't realize that bar was clickable'). They are also much more restrictive than software UI's - so the designer really has to put in effort since you can't replace the hardware interface by putting out an update. I can't resist to draw a parallel with programming. In the early days, where binaries consisted of carefully handcrafted code, they were in the range of kilobytes. Nowadays programs are in the range of megabytes to gigabytes due to all the libraries that are statically included (and possibly duplicated). When I install Xilinx ISE (no support for anything above windows 7) or Visual Studio (both 2015 and 2017, because both have features that the other one does not contain), I have already used more space on my SSD than I'd like.
