One could say the Cell was a success because it "saved" the PS3 from using a sub-par GPU (compared to X360) and allowed the console to attain graphical parity with its competitor.
Or.. one could say it was a total failure because it was presented to the world as the future of media-oriented computing, is the result of a brainstorming and R&D aggregate from three of the largest tech companies in the world (Sony, Toshiba, IBM), about $400M were spent to develop the chip and in the end... it apparently leaves no direct offspring.
If 10 years ago Sony, Toshiba and IBM could know the current state of CPU and GPU evolution, would they develop the Cell anyways?
Probably not, IMHO. It would've probably been better for Sony to just get an off-the-shelf PowerPC/x86 CPU and spend a larger piece of their R&D and power budget on a more future-proof GPU.
Actually, Toshiba has a chip called CEVO that they made primarily for their TVs and it's a direct offshoot of Cell tech.
