The original 'dying systems' remark was obviously kinda snarky, but there's still worlds of difference between PC and consoles in that regard.
Of course, it was, I confess Nobody wants to accept the fact that his new shiny 300E box is short lived, but platform longevity is related to manufacturer support, not on how long the hardware can survive. I am pretty sure you can find some pre-NES console units in working stage, it does not change the fact that as a platform, they are dead.
