That's the hardware cost.  How many watts does it consume?  Cooling a PC is hard
enough nowadays; why would an engineer include a component with "oven" in its
name if he didn't have to?  Also, how many people really need that level of
accuracy?  If hundreds of millions of PCs are consuming watts they don't need,
that's wasteful on a pretty grand scale.
