I just got my free upgrade copy to Office 2008 Special Media Edition. It's incredibly slow. I'm using it on my current 2.4 GHZ iMac with 3 GB of memory. Sometimes the applications open in decent times, others, especially powerpoint, takes forever. Furthermore, once they are open, the program is unresponsive the next few seconds, and sometimes in the middle of doing something they get sluggish. Any ideas? Are all of you experiencing this more or less? I sure won't be putting it on my G4, since my 2.4 GHZ Core 2 Duo can't seem to handle it. ha-ha.
