In a move to boost sales for their new 15″ Macbook, Apple has officially ceased production (and sale) of the 15″ Powerbook G4, leaving only 12″ and 17″ versions available to consumers. They have already removed it from the Apple Store.

If you were hoping to get your hands on one, Amazon still has some in stock, and is even offering a $200 rebate on them.
