One big problem was the epic power consumption of the Itanic CPUs. I remember going to a corporate presentation by Intel about the revolutionary CPU architecture. They had to turn the machine off because the cooling fan was making so much noise we couldn't hear the speaker. And this at precisely the wrong moment in history, as mobile devices, with their stringent power consumption constraints, were becoming popular.
