No, this highlights that electricity is virtually all of the TCO over the life of the device. It doesn't sound like you've done a lot of TCO work before. In any case we're talking about facilities containing tens of thousands of these devices, so the TCO of one of them is irrelevant.

I don't understand your point. Yes, electricity is virtually all the TCO of the device (other than the upfront cost). Isn't that the case for any consumer electronic part - processor, memory, hdd, etc? That fact doesn't change any of what I'm trying to say.

My point is that this cost (of electricity) is negligible relative to two other costs - cost of time (in other words, cost of human capital), and the upfront cost of the device itself.

This is a response to your comment "Wait, why? Is it more important to organizations to wait a little less time, or to spend less money (on electricity)?"
