My condolences Thomas.

My rule of thumb is that if I have to work hard to remember how to use a function on a camera, that function is an afterthought, and is just as likely to impede good photographs as it is to enable them.

This is at least partially due to the fact that I have too many cameras.

It also means that some camera designs are way more successful then others. As an example, I refer to something like a self timer. I use my self timers regularly (in lieu of a cable release). By far and away the best design is on my Olympus OM 20. In contrast, on my various Canon EOS bodies, it is always a head scratching moment to try to find the setting, much less figure it out.

And don't get me started on "menus"!
