@millan No offence taken. I have taken apart anything technical since I could hold a screwdriver as a hobby and like to tinker and design stuff to be better and more useful than before. Also I work as a technical designer professionally and I have a lot of responsibility to make the right decisions, because a bad one could put our company into bankruptcy. Also I live in Finland, the one dealer that sells and maybe services is about 600km away. I additionally upkeep two cars, a house, garden, family, career, etc. That being said, I do a lot of things myself that use up my energy and time. It is not, like you suggest, that I have not learned to do repairs or tinker with stuff. Rather, what I apply professionally and in personal life, making things better and optimized I also apply in my critique to manufacturers or providers of services etc. In terms of life cycle, environment and autocracy issues I do, and I stand behind this 100%, value serviceability and any steps a service or product provider takes towards making this as simple as possible. It is one of very many design criteria that should be taken into account. For me, the tiny hands was not really the main issue that I got caught up on. Edit: I would like to add that for 10+ year I have been responsible for using, programming, calibrating, repairing and acquiring industrial CNC equipment, and even making those machines do amazing things they were not even designed to do. Without a professional training and without a teacher, only from handbooks written in bad english.
