G4 for FACSCalibur - and a plug for Mario!!

Like you and many others in this world, I have one of the other 90% of the
computers at home.  I do not like it, but the other major occupant of the
household (my wife) required it for her job.  However, like 90% of the Folw
Cytometry users out there, I have a BD instrument that uses a MAC to acquire
and analyze my data.  So, I subscribe to the "do work at work" theory and
use the MAC, which by the way I do prefer.  Mario's (and Adam's) FlowJo
software is a very nice alternative, and any software that is an alternative
to paying big bucks to certain Flow companies should be most heartily

So, let Mario plug away and let the users of the minority instruments tout
their advantages if they wish as well.  That is, if there are any???
