Apple Russia has kicked off a new promotion that offers Mac users a discount on a new Power Mac G4 when they trade in their older Power Mac, regardless of model. The discount varies depending on the model of Power Mac G4 purchased: US$180 for the 800MHz, $265 for the 933MHz, and $355 for the dual-1GHz. The promotion runs through the end of June and can be combined with other promotions. Macintouch notes that the promotion could be making its way to other European countries.
