Apple has apparently begun shipping Mac minis with 1.5GHz G4 processors. Customers who recently ordered the top-of-the-line 1.42GHz model instead received the updated machine. Users claiming to have received 1.5GHz machines indicate that it ships with a 64MB Radeon 9200 video card and an 8x SuperDrive. If Apple has indeed transitioned to 1.5GHz chips for its high-end Mac mini, it would end weeks of speculation about a quiet rollout. Apple has not updated its Mac mini literature, nor has it updated the Apple Store to reflect any changes to the Mac mini lineup.
