[citation][nom]jimmysmitty[/nom]Considering that IB will be 22nm and utilize tri-gate tech, I am sure that battery life will jump up quite a bit. If they implement power gating as well like in current gen Atoms, then they can probably achieve 12 hours.[/citation]
the new gateing could increase over all preformance per clock, and allow for smaller processes, but it may also improve high clock power useage.
not quite sure beyond that atm, but assume its one of the two. more power per clock = lower ghz processors, also cooler processors, and more battery, better power usage, means higher clocks with the same or lower battery usage.
personally i despise these kinds of computers, as they are only about as powerful as a netbook but because they have "style" you pay 2-4 times their real worth.
