Several readers noted that they received delay notices from Apple today for their PowerMac G5 2.0GHz systems. The new delayed date was cited to be October 14, 2003.
However, one reader reports that after speaking to an Apple Representative today, only some orders were supposed to receive this delay email, while other orders were to get shipping notices... but unfortunately everyone was sent the 'delay' notice.
This particular reader was told that his machine should be shipping today. Your mileage may vary.
