"With its new Joybook Lite U121 Eco, BenQ becomes one of the
relatively few vendors to turn to Intel's original Z5xx-series
Atoms, with their SCH US15W combination northbridge/southbridge,
for a netbook. Though more costly than the typical Atom N270, the
Z5xx Atoms are smaller, use less power, and include 720p video
capability, according to Intel.
"BenQ's U121 is offered either with a 1.33GHz Z520 CPU, or a
1.6GHz Z530, both with maximum power consumption of 2 Watts and
idle power of 100mW, according to Intel ratings. According to BenQ,
purchasers of the Joybook can select either a three-cell, 2600mAh
battery, or a six-cell 5200mAh battery, gaining four- and
eight-hour battery life, respectively. The device's "Q-Charge"
circuitry can charge either battery to 80 percent of its maximum
capacity in just an hour, the company claims."
