MacMinute has learned that Apple has added previous-generation 600MHz iMacs (Blue Dalmatian M7675LL/A, Flower Power M7679LL/A, and Graphite M7680LL/A) to its Snap It Up promotion, which offers customers a US$150 rebate or free HP PhotoSmart 318xi digital camera. In short, all 600MHz and 700MHz iMacs that are purchased as new are now eligible for the promotion. Apple has yet to update its materials with this information, however.
