You're right about that. As I said, I mainly use it for longer meeting agendas, such as conferences with several speakers, so we're not fumbling around with closing one presentation, searching for, and opening the next.

I have found that hyperlinking worked fine in Win XP with Office 2003. I was never able to get it to work at all in Vista, but we skipped that version. It works again in Win 7 and 2010. (Also works on Lion and Mac Office 2011, but that's really a minor point, we're a Windows shop at work.) Also, like I mentioned earlier, you have to be sure that you don't have slideshows set to end with black slide, which is the default.

I heartily agree with you here! Just because you can do something, doesn't mean that you should. I was replying to the OP about a way that you could do it.

PowerPoint is essentially a landscape medium. No matter what you do to the slides, the screen on which you are presenting stays the same.
