It could be either of your options. I use mine twice a week, but judging by the number that turn up in charity shops, there must be other people who never used them at all.
They are definitely NOT faffy and complicated. You measure the ingredients, put them into the machine, select a few options (size of loaf, how dark the crust is, etc) press "start" and leave it alone until it beeps that it is finished. About as complicated as shoving your dirty clothes into a washing mcine, adding detergent and rinse aid, selecting a programme and starting it off.
If you are happy with the basic loaf, you can make that every time and enjoy eating it. If you are more adventurous, you can use different flours and additions - there are plenty of recipes.
I suspect quite a lot of the one in charity shops were unwanted Christmas presents, or belonged to someone's late mother and inherited by a daughter who didn't want it.
