The fastest laptops usually get lousy battery life, but Asus has made a few innovations that supposedly net its memorably named UL80JT laptop an incredible 12 hours of battery life, despite its Core i7 processor. I really hope it's true.

The big change here is a real-time management system that re-clocks the processor on a moment-to-moment basis depending on what you're doing, which means light work should result in light power usage. That's how it can hit 12 hours of battery life despite the Core i7 and its Nvidia GeForce 310 GPU. We haven't been able to test it yet, since it was just announced at CES, but here's hoping the claims are anywhere near true. [Ars Technica]
