Harry (a while ago) posted about his view on slides - try not to use them. Which I generally agree with. Of course, to show differeing views Sascha wants to make sure appropriate use of slides.

While preping for my MDC session, I got the advice that for a big talk having some slides to orient the audience is a good thing. Originally we were thinking of having absolutely no slides in the presentation - however with 45+ minutes of demos (mostly coding), I think 5 minutes of slides should be tollerable.
