Powerpoint practicing- Favorite designer

I used to do lots of presentations when I was in Vietnam, so I am kind of used to PowerPoint (PP). It is actually not difficult to use, and I think it is a perfect tool for doing presentations. With PP, we can play around with texts, pictures, and different presenting styles. By putting main points into different PP slices, it helps a lot while we are presenting. However, no tools can replace skills, of course.
