I'm satisfied with the overall speed of the Creative Suit 2 in Rosetta on my Mac Pro, but it turns out that Illustrator is incredibly unstable. Every time I either use a raster effect (drop shadow, etc.) or click any button at all on the Pathfinder pallet, it Unexpectedly Quits. Not actually 100% of the time, but probably 90% of the time. That's what I've found so far, I'm sure there are more things that can crash it though. This is obviously a bit of a problem. I'd rather have it run slow that crashing every 5 minutes. 
Yeah, all latest updates are installed, etc etc etc. No problems with the other apps (mostly Photoshop) so far.
