You are misinterpreting that. That is the display _only_.  Not the 
system power.

And the EC, the memory, various pull up/down resistors, and few other 
suspend voltage regulators.  All these add up to a non-trivial amount.

Claiming that the power draw of the display unit in e-book is the system 
of draw of the laptop is inaccurate.  It will be close if you were to 
throw up a page and let it sit there and never touch it.  But the moment 
you engage the cpu to flip a page you draw 5-7x more power.  The average 
  draw then depends on how may pages you flip.  We do not yet have any 
metrics for what that will work out to be.
