Take anything Michael (phoronix) says with an entire truckload of salt. The "thanks to" conclusions are unrealistic, simple matter of the hardware that ships with new laptops. Not too many nvidia laptops these days, and really, why would there be since we're moving towards APUs now.
As for those units with dual graphics (which will have something like INTEL IGP + DISCRETE NVIDIA, or AMD IGP + DISCRETE AMD), the discrete chip will only get switched on by gamers, since it doesn't yield any benefits for non-gamers and eats up extra battery.
My laptop is a dual-AMD. The discrete is switched off and won't be coming back on unless/until there is some practical (i.e. OpenCL) use for it.
