"When was the last time you used a piece of chalk to express yourself?"
Last week. Whiteboard marker, to be precise, but if we had a blackboard in the meeting room, it would have been a piece of chalk.
Everyone who knows something about presentations also understands that Powerpoint is a horrible abuse and failure in at least as many situations as those where it is a useful tool. There are things that you can best show in animated slides, others are best described with prosa text, yet others with short and memorable phrases. In addition, everyone learns slightly differently. Some people can't remember anything in a lecture unless they take notes while for others watching all the slides or the scribbles on the blackboard is the most important and for yet others hearing the professor / teacher / workshop-giver is the main part.
The so typical and almost always wrong our-one-size-fits-all Microsoft approach will not solve any problems, it'll make it worse.
If kids these days don't know how to express themselves with pen & paper, then maybe that is something you should teach them? It's a useful skill, and even though I've been a computer guy since the C64 was state-of-the-art, for some tasks I still prefer a notebook over any iPad app, and the reasons are purely practical.
