There's never a convenient time for your notebook to run out of juice when you're on the road, yet somehow the low battery indicator always manages to pop up at the worst possible moment. Like after boarding a cross-country flight, as opposed to five minutes ago when you sat in the terminal right next to a power outlet. Nvidia's Optimus technology won't prevent such a scenario from playing out altogether, but it does offer a bit of insurance against Murphy's Law, giving you more time in between charges by intelligently switching between integrated and discrete graphics depending on the load. And it's now available on Maingear's Clutch-15 notebook series.
