I disagree with the OP. As much as I am a PC gamer (and Nintendo gamer if you have not guessed from my avatar), I think having a home console platform that sets the standard for devs with regards to graphics is important. If we only had the PC market, a lot of devs would target low-end GPUs like integrated Intel cards because that is what most people have.
My wish for Sony is to continue making dedicated portables again so that there continues to be two viable dedicated portable gaming platforms on the market. So if anything I want them more involved in making hardware.
