Anybody interested in seeing XSI ported to the new Pentium Duo line of Apple computers should probably send an email to Softimage, preferably sales@softimage.com because those are the ones who might make a difference if they get enough emails...
I recall the repeated response of Alias to questions about a Mac version of Maya was always "We have no plans to do a Mac port at this time" right up until they announced they'd be developing a Mac port. But when they announced it they said it was "due to the volume of requests for a Mac version" so apparently democracy works.
