I mean it was designed to (And did succeed at times) offload many of the GPU's tasks and act as almost a second mini-GPU.
This allowed TLoU and Killzone 2/3 to make the games on 360 look half a gen behind, and games like BF4 got higher levels of MSAA on PS3 since the cell could run. Whether or not it was worth it in terms of programming is up for debate, but imo where it really was a waste was cost. I mean the PS3 would probably cost $20-$40 less right now if it wasn't so damn expensive to manufacture the CELL.
Prediction for console Lifetime sales:
Wii:100-120 million, PS3:80-110 million, 360:70-100 million
[Prediction Made 11/5/2009]
3DS: 65m, PSV: 22m, Wii U: 18-22m, PS4: 80-120m, X1: 35-55m
I gauruntee the PS5 comes out after only 5-6 years after the launch of the PS4.
