Hello, I was wondering if the Kiosk's could run unsigned code. If so I might consider getting one. (Sorry if wrong section )
I'm fairly certain that the kiosk units are just standard retail units with the Medusa control box, seen here http://www.assemblergames.com/forums/showthread.php?42567
As mentioned Kiosk units are retail units, the Medusa box basically signals to the Xbox that it should not quit, allow you to connect to live, etc. The only time you may get a reviewer unit in a Kiosk are at trade shows and the like but these will be marked as such.
