I know a lot about MS Office and honestly, since the menus changed to icons in the 2007 version, there really hasn’t been a big difference.
While in a presentation (about 2 weeks ago) I was an advocate for MS Office, specifically PowerPoint. I feel that is may be a stepping stone and a good offline alternative to presenting. The tricks and presentation skills that you learn may be transcended to that of emerging technologies like Prezi, etc.
What do you think?
