I have to create a presentation for one of my classes, and I need presentation software. I'm torn between Keynote and Powerpoint for Mac OS X. I am running OS X on a 333MHz iMac, and Keynote requires at least 500MHz. My system meets all the requirements for Microsoft Office v.X, but I would like to use Apple's product if possible. Does anyone know if Keynote would run well enough on a 333MHz machine? Also, if anyone has experience with both apps, which would you recommend? Thanks.
