In my view LF is worth it. I spend years wasting my time with 35mm completely frustrated at the unacceptable, to me, image quality. It was Ansel Adams' fault. I saw an exhibition of some of his photos in Liverpool back in the 70s, I think it was. When I compared my efforts to his, it was to use a football comparison, The Bash Street Kids team playing Manchester United, other top teams are available to support

.
After that I pretty much gave up serious photography until the early 2000s came along bringing digital. Suddenly the price of LF gear crashed as everyone switched to digital and along with being older and slightly richer I could suddenly afford LF and for my photography it changed everything. The cost of each photo was significant even then, so it made me much more thoughtful about each photograph. No more taking lots of shots in the hope something somehow would come out which it rarely did.
As a result of this approach my success rate soared and I achieved many more photos that satisfied my aspirations. I have now moved to digital simply because I find it too onerous to cart a heavy bag of LF gear around now I am over 70. These days I seldom go on planned trips to specific locations with the aim of taking photographs of that location. Nowadays, my photographs are found whilst out walking, so LF isn't practicable for me and I have devolved, some would say downward to digital, where I can get the same high resolution, which is important to me, without killing my back.
Incidentally, someone mentioned AA using a Hasselblad, but that was because he too was finding lugging LF gear too much effort. I guess he would probably have preferred to continue with LF if he could have.
Anyway, I digress a bit. What I am saying, in a slightly long winded way, is that using LF gear has influenced the way I use my digital photographic gear. Apart from from using back button focus because I can't trust my eyes anymore. I use the camera entirely in manual and endeavour to treat making a photo with the same care and thought as though I was using my LF camera. I think if everyone spent a while using LF, even if they didn't stay with it, the standard of photography generally, would improve all around.
Like Joanna, I still get my LF camera out play with it, stroke it etc and dream of taking photos with it, because in my heart LF feels like proper photography in a way that nothing else does.
