embedded products often use non-cutting-edge fabs - it really 
depends on the whole set of price/performance/heat/reliability/volume
tradeoffs.  for instance, a "mature" fab tech will often have much
better leakage control than when it is young - for a single line 
width, etc.

so O($5)/year (assuming $.15/kwh and 1% duty cycle).  is this a real concern?
engineering-wise, it's a lot nicer to fit such a system inside a 
50-100W window, which is what the current rumors sound like to me.
