Why?
Is this to remind yourself that you're running Rosetta? Or is there a performance advantage? ---

Why?
I, too, would love to hear if there is an actual performance advantage to this tip. Otherwise, it's just an exercise in OCD behavior!
Why?
There's no performance advantage. The only way there could be is if an application is a universal binary and is set to prefer PowerPC over Intel architectures, and there's no reason to do that. Any PowerPC-only apps wouldn't work, and any universal apps should always run as Intel anyway. If you do have a universal app that runs as PowerPC on your Intel Mac, you should complain to the app's developers.
Why?
I think that the performance advantage comes from never running Rosetta. An application that can be run in both Rosetta and regular mode will run slower in Rosetta (you can test this yourself by choosing "Open using Rosetta" in a supported Application's Get Info window. I am not sure how Rosetta works, but it may create an overhead on the system in general if any application is using it. Although it doesn't seem to run as it's own process. I think it might be a low level thing that dynamically translates PPC machine code into Intel machine code.
Rosetta process is the "translate daemon"
It is its own process. Look for
translated in your ps -aux listing, or in Activity Monitor.
