but powerpoint presentations will never replace a good slide presentation in my book[/quote]
This is interesting. I was of course joking about slides. I make Powerpoint presentations all the time and the slide/carrousel era, although not so far away, just sounds like middle ages, if not prehistory. But I had never realized that slides can achieve higher quality. Just like some believe that CDs will never quite match the quality of some vinyl records...[/quote]
What made slide shows superior to power point presentations is that 99% of the slide shows I attended were a success, that is, they worked. I have attended about a hundred power point presentations, and I can remember one that functioned. The others ranged form almost working to having the presenter hold up her notes so we could see the photos. The medium is not to blame, it is the people who think that modern technology is the draw, and not the material presented. Most of the problems with power point is because the presenter does not bother to learn how to use it.
Now a comment about CDs. We had a young man from Germany spend a year with us in the 80s, he was buying CDs even though he did not have a CD player yet. He told me that CDs would never be obsolete (I was and am a cassette man myself). We attended his wedding in 2008, and I mentioned to him that CDs were obsolete, he looked at me like I was an idiot. I said "no one has CDs anymore, they all have ipods." He aged 30 years in about 10 seconds.
