While the world is still waiting for the $75 laptop, the same company is working on a raising cell phone and notebook battery life to 20-40 hours. We’re not dogging Pixel Qi for trying to develop killer tech, but all it seems the start-up is good at is writing press releases at this time. As for the laptop battery life, it’s extended due to a new screen technology that reduces power consumption while maintaining a quality image. Who knows when this will hit the market so don’t postpone your next purchase waiting for these low power screens; the $75 laptop was announced last year and is no where to be seen.
