The latest Apple Event about the iPAD in January is a very nice example why uncluttered slides are important. See this shot from the official Apple Keynote, lowes resolution, screencaptured and low qual JPGed:
No problem at all to actually READ whats written here. And get the message, nothing is unclear, cluttered or “between the lines”…
I watched the keynote “live” through one of the many streaming sites. Really bad quality, not surprising from a handheld device located in the audience, with limited bandwidth. In parallel I watched a also streamed live broadcast of a corporate event. Even tough that was streamed with much higher bandwidth and resolution, I was not able to read a word from the slides. At the Steve Jobs show that was not a problem. Why? Reduction to the max.
It follows: How to improve your slide deck AND put you in the center? Start with changing your mindset: Dont think what you can add, think what can be deleted. You are the messenger, not the slide. Not Powerpoint, not Keynote, not Impress. You!
