An article in the December 2004 issue of MacWorld on presentations stated that "iBooks in mirror mode may not be able to keep up with presentations that include lots of complex movies and transitions. In that case, leave them out of your presentations." I have a 2001 dual USB iBook and wonder if it will be able to handle presentations with a projector. I have a G5 iMac where I intend to put together the Powerpoint presentations so I will only be using the iBook to present them. Any thoughts and experiences would be appreciated. Derek Boles
