Maybe it's just being on a team that's more focused on nontechnical users, but I still see plenty of PowerPoint. Product, sales, and business process people seem to swim in the stuff.

When I was with AWS last year none of our meetings followed this type of structure. Someone put together a presentation in PowerPoint if needed, went through their items, people asked questions and action items were assigned. Pretty typical of any company I've worked for. Although I thought there were too many meetings to attend which took away many peoples development time.
