What the hell do you do to computer hardware. There is almost no real difference in the mean life time of the components of a console vs the components of PC's or Macs. This is even more true these days since consoles use more and more PC or customized PC hardware.
I suppose it's because people don't perform maintenance on PC's. Over time they slow down, and instead of fixing it, people just buy a new one "because it got too damn slow".
Consoles don't really need that, do they?
