Do you ever run into problems where all your content won't fit on a slide and it cuts off when exporting? I guess you can just go back and compare your slides to your outline in OO, but I'm wondering if it may be better to compose in Keynote for that reason (as you said, maybe not if you need it for other purposes).

Of course, I shouldn't be trying to cram too much text onto one slide, but in some cases you might be going slightly over. Doing it in Keynote might save some work in getting your slides ready, but I do like having the whole outline to work with in OO.
