ArcGIS for Office can be an option, even after its buggy interface. For presentation, I don't worry much about putting everything inside powerpoint. Powerpoints should be lightweight and focused at the same time, leaving the technicalities. I start with the bullet points and tables, and later jump to the truly technical session. Since I usually face a lot of eager questions every time I present, I usually leave ArcGIS Desktop and Google Earth open in the background with all maps loaded. For more - "... please talk with me after this presentation".
I don't even bother to export, the mighty 'snipping tool' does the job..
