Unlike many industry suits, he at least has inside technology knowledge into what makes a console thick. Remember that beloved SNES of yours? Without the audio processor Sony SPC700 that Ken Kutaragi designed secretly from his bosses at Sony, you would not have classic SNES soundtracks like Final Fantasy VI. Like the rebel he was, he was also critical of Sony's love affair of DRM (way before Steve Jobs jumped on the anti-DRM bandwagon), which many believes was the reason he was demoted from his position at Sony.
Without Ken Kutaragi, consoles would still be viewed as the toys they once were. As a fellow gamer I wish him success in his future endeavours.
