I bought one for my wife and she loves it. She is a big TRON fan, but most of that is because of the Legacy soundtrack by Daft Punk.
We use this on a mac, and there is no software or drivers for mac. The mouse works, and the DPI switching works, but no software.
Here is a link to the drivers: http://www.razersupport.com/index.php?_m=downloads&_a=view&parentcategoryid=98&pcid=87&nav=0,87
Only windows is officially supported, but, like i said, it still works.
