Step in the shoes of an average user. You have to create a good looking document. As usual, there is time pressure. You would have no idea where to look online for templates, let alone create it from scratch (master page, huh, what?). In powerpoint or word, just pick one template or theme and it looks slick.
Even when you import a template in Impress, you will find some weird bugs, like a slide insisting that it won't show the slide number. I found such random weird behavior that I wouldn't even know how to file a bug report for it, because they are impossible to reproduce.
----------------------------------------------
I know the stuff is built on top of some very ancient code. Sometimes I wish they would throw it all away and start from scratch in a modern managed, type safe language. It would be feasible if you forego backwards compatibility as I suppose a lot of the bugs have to do with trying to support the MS Office bugs. A consistent finding is that LO supports older office documents better than MS office itself.
