The paperwhite is a nice display, and part of the benefit they claim is that the light guide combined with a matte screen reduces the amount of backlighting needed, thus improving battery life. That may be - but another big factor is the relatively anemic chip compared to phones / tablets / laptops. All that aside, I really wish this kind of deliberately misleading comparison would die: http://g-ecx.images-amazon.com/images/G/01/kindle/dp/2012/KC/battery-compare._V389693466_.gif http://g-ecx.images-amazon.com/images/G/01/kindle/dp/2012/KC... Why are laptops and tablets and smartphones measured in raw hours, while the paperwhite is measured in weeks, where one day is half an hour? And then why plot them on the same graph, indicating that they mean the same thing? A graph that wasn't intentionally misleading would show the paperwhite with a bar about 2x the length of the smartphone's - in practice, it gets about 11 hours at full tilt, and about 28 (that's 56 days * .5 hours per day) when conserving power.
