The problem with that E-Ink is expensive, slow (you can't 
  have moving cursors or any kind of video) and boring.

The price will decrease once the technology behind its production improves (and people stop there willingness to actually spend that much), it will also speed up over time (its just how things work. To address the last point: WTF?

Secondly, from the Pixel Qi site:

  Our screens use 1/2 to 1/4 the power of a regular LCD 
  screen, and when integrated carefully with the device can 
  increase battery life between charges by 5-fold. 

and from Giz:

  Jepsen says it's even possible to get a week of battery 
  life from LCD tech, of course depending on the device the 
  screens are embedded in.

I really don't see how those two can statements can coexist. Currently we get around 8 hours from labtops, improve that by her 1/4 estimate and we now get 32 hours which fall short of our weeklong estimate.

Lastly:

  Infrastructurally and perhaps historically speaking, the 
  odds are in LCD's favor.

I'm going to need this one spelled out for me...
