Hailstone Software did some tests on RAM usage of Rosetta, and the results are quite interesting. While it took me a little while to figure out what the chart and numbers meant, essentially, it comes down to this: Rosetta is memory intensive, taking anywhere from 2x to 5x the amount of memory that a PowerPC native app uses.
This also explains why Adobe Creative Suite on the MBP runs sluggishly compared to the PowerBook G4s -- CS was a memory hog even before Rosetta started to take even more RAM to contain the app.
