The choice of two different screens (and techs) on one device serves to overcome the shortcomings in e-ink, which lacks of richness and interactivity; and LCD's eyestrain and battery drain. (The LCD will remain inactive while books are being read.) Contrast this with the Kindle which uses the e-ink display to emulate a slow menu system and requires a physical keyboard for searching. Likewise, Sony's e-ink readers with touchscreens layers have reduced visibility. The B&N reader has none of these issues. [editor's note: In theory.]
