"This interview starts off with Kutaragi offering a reason that the PS3
made use of a specialized graphics unit (GPU) from NVIDIA (the RSX),
rather than a GPU based on the Cell processor. "The seven SPEs
(Synergistic Processor Element) of Cell can be used for graphics,"
reveals Kutaragi. "In fact, many of the E3 demos were made without a
graphics chip, with only Cell used for all graphics. However, this
means of use is wasteful."
Kutaragi reveals that there was once the idea of using two Cell chips
in the PS3, with one used as the CPU and the other used for graphics.
However, this idea was killed when it was realized that Cell isn't
appropriate for the functionality required for shaders, software tools
that are used to draw images to the screen. The decision to go with a
separate GPU was made in order to create the most versatile
architecture possible."

Sounds like common sense to me.
