The main reason I never stick with TODO applications is because I can't get into the habit of using it. I often think this is why so many persist with email as a todo list.
Not that I've ever done that..
For example, see here where I had a general bug, took notes, got quotes, and (as someone above mentions) attached photos of fireplaces.
Doing so on a publicly accessible (and modifiable) bugtracker means you get a social / collective intelligence (and collective stupidity / vandal) effect. More useful for community projects than home ownership, but still.
I've seen workplaces where non-software issues (often facilities / maintenance) were tracked and managed through bugtracking tools.
