This isn't going to end well for Asus. Early adopters of the Eee PC 900 in Hong Kong are in a spat with Asus over batteries. Seems the Eee PC 900 ships with a standard 4-cell, 4400mAh battery whereas the battery shipped to the Hong Kong media (and presumably others) was a 4-cell, 5800mAh; the latter Asus is calling a mistake. That would certainly account for the wide ranging Eee PC 900's battery life reviews which have varied from a very disappointing 1.5 hours to a decent 2.5-hours
. Of course testing methods will also contribute to lifespan. Regardless, ASUS is now considering giving 900 buyers a free upgrade. Our suggestion? Just do it Asus, and pronto. Else the Eee PC brand you've become so dependent upon is going to take a serious beating.
