In principle I agree with you 99percent of the time, as descrete slides define the pace of the lecture, but at the same time I'm against arbitrary limitations. And not being able to scroll is imho such a limitation. Here are a couple of examples that I believe justifies scrolling:

* A code listing. Splitting up a listing between two pages looses contents.
* A tall graph, e.g a flow chart.

In this sence I think that htmlslidy is better than s5.
