That in fact seems to be *your* most serious impediment to
improving your photography.

I am curious how you come up with this. To me, it's like saying a
better developing pan will lead to better photographs when working
with film.

the advantage of a more functional operating system is the availability
of more functional apps which can produce better results.

better apps can also greatly increase productivity, which means fewer
hassles in producing the results, leaving more time to concentrate on
photography itself rather than the processing.
