Even in very optimistic estimates, the battery conservation potential of Pixel Qi is limited. You're not saving 10x the power like they said on Engadget. You're not saving 4x the power. You will be lucky if you get anywhere really close to 2x the battery life, which may push some devices into the all-day-usable realm for some users.
I'm simply saying that this is not the same kind of thing as dedicated e-paper technologies. It's not marketed that way, and it is a bit unfair to include as an especially similar product, especially when it comes to displaying fixed content.

Yes, 5 times less than 2500mW is 500mW. They are hoping to get down to around 100mW. Static content in e-paper like EPD or IMOD is less than 1mW. According to
this (whose accuracy I can't immediately confirm or deny), the reflective LCD in the jetBook pulls around 20mW.
