Other than HALO the Xbox was a weird system in that it really hit its stride IMO in the last couple of years -- towards the "end of its lifespan." One could argue that they should have kept at the original Xbox for another 12-18 months because to me it really hit its stride late in its cycle. Obviously they have their reasons for the 360 launch right now, but it seems like it may be some time before they get a "killer app", while the original Xbox still had some life in it.
