Seems Stata is slower on the Mac OS X. That's been my perception. It's 
kind of strange considering other tests show the Opteron and G5 as a 
pretty close match:

That aside, does anyone know about any laptops that run the Opteron? 
Has anyone got Stata for Unix to run on such a laptop if available?
