> I guess what's going on here, the reason people are divided, is that on software that you dislike (or are forced to use) people generally hate settings and just want the thing to work. On software that people love (like a piece of software that helps you make music or edit video) then people generally enjoy being able to customize it further and further.

I don't think that's quite it. I think the ability to set the software to work the way you want it to can turn a piece of software from one you dislike into one you love. [EDIT:] Or, vice versa, the lack of the ability to do so can turn a piece of software from one you would have loved into one you dislike. [/EDIT]
