So this is benefit for developers. Another benefit is for Mac users, that they run single app regardless if they run on PPC, i386 only Intel (first Intel Macs ?!) or latest 64-bit Macs.

That is fair enough. Do other users have an opinion either way?

You can simply run

lipo -create /Applications/R.app/Contents/MacOS/R \
 /Applications/R64.app/Contents/MacOS/R \
-o /Applications/R.app/Contents/MacOS/R 

That will create the 3-way universal R.app as discussed.
