I was disappointed to find during my first live Keynote presentation 
that I couldn't drive the projector from my TiBook 667 because I only 
have 16MB VRAM - this is the last pre-DVI TiBook 667.

I didn't have time to play with the Keynote or video settings at the 
time, but fortunately I had saved copies in PowerPoint, PDF, and 
QuickTime formats. While QuickTime made for a huge file (16MB vs 900k 
for Keynote and 600k for PowerPoint), all the Keynote transitions 
carried over and were viewable on the projected image. QuickTime saved 
the day!
