My dad used to work for an IBM associate company...he said they have so much technology just sitting on the shelf waiting for other companies to catch up...when they do, IBM pull some tech off the shelf and presents it.
He personally saw the architecture for the Power4 about 5 years ago not mention heard about the organic LCD display technology and the laser manufcturing method for making LCD screens...they had ready to go a couple years back. But IBM figures...no sense in competing with themselves...
