I think a fair response to that is to distinguish between the micro and macro. Choice of font is arguably a micro-level trend; the presentation is dealing with issues on the macro, whole-of-page scale. The presenter of course has to choose a font, and he can be forgiven for not choosing Times Roman, Courier or Tahoma. What he did choose is a font that, while currently in vogue, is still eminently readable. As for the drop shadows, they also aid readability within the context of the chosen aesthetic. (And they're definitely not 1px -- probably closer to 5px by the time it's scaled up for a high resolution projector -- the shadows are proportional and appropriate for the weight of the strokes.)
