I wonder why no one mentioned application of this technology in mobile phones. Most obvious case: it will be posible to bring entire system from hybernate state while user pulling phone from the pocket and pressing "awake" button. Power and computing cost of hybernating/restoring system would be slightly north of zero, which leads to dramatic increasing of battery life. Not to mention size factor and lower power consumption of chip itself.
