I started using S5 for a presentation and I quite like it so far. However, I have seen a few other systems being mentioned such as S9 (which is, as I understand it, an extension of S5), Slidy and a few others.
I'd be intrested what the differences are between all of these. I'd also like a motivation to why you think one of them are better?
I'd also like to know what the main advantages of using S5-generators such as Sphinx. I'm currently learning Ruby so that vista is open as well.
I find S5 very easy to use but I want to know what the alternatives bring.
