IMO, PixelQi is a step forward for notebook/laptop screens, it's not really a direct competitor to eInk.

It actually boasts higher contrast (12:1) than e-ink (8:1).
You're right that one disadvantage is higher power drain, but not significantly higher. Like an e-ink screen, the PixelQi screen in epaper mode can display an image using no power at all. Since the backlight is the main power drain on non-eink devices, eliminating the backlight is expected to increase battery life by 5-fold.
