the answer is that the crank ended up being fragile, and not that efficiant, so what they did was to make the laptop _extremely_ forgiving on it's input power (something like 7-30v tolerance and charging best on 9-15v), so it can get power from very dirty sources.
the other thing is that a person cranking can produce more power than a single battery can efficiently absorb, so the emphasis shifted to charging several batteries at once, and produce a large number of different chargers.
they have string pull chargers (think lawnmower)
bow chargers (think old western fire starter moving the bow back and forth)
solar chargers
as well as many other charger designs (wind, water, animal power, etc)
as far as the screen goes, my understanding is that it's cheaper to produce than normal LCD screens (it has 1/3 the pixels of a conventional screen of the same nominal pixel count while having ~3/2 the effective resolution in color mode), it should hit the market in other devices Q1 or Q2 of 2009
