I'm using a Aluminum Powerbook 1.25Ghz, 1 GB Ram, OS X 10.3.8. PowerPoint is very, very slowwwww when I type text ( it took about 2 seconds to display a character ). I've installed the lastest update but nothing changed. Most other applications can run quite fast ( not very fast but acceptable). This Mac can run heavy games like UT2004 well so I assume it is a fast machine. Any idea ?
