But how is it at all enlightening? Anyone who looks at the charts can see that the reason that the PS3 is at 1m so soon is that it got an absurdly large launch spike, and that sales have now settled down significantly.
It's total sales and long-term sales rates that we ought to be interested in - it's far more informative to say that the 360 has about three times the install base and is selling faster than it is to say that the PS3 got to 1m more quickly after launch, especially when it's obvious that it beat the 360 largely because of shortages, which have no real effect on long-term sales.
