By telling us that you only have to charge your phone twice a week, they're telling us that a Poet IC will save you up to 350 per cent if you charge once a day up to 700 per cent for those that charge up twice a day . The power savings is not only in electricity but more importantly in chip processing efficiency. That's what the industry wants to hear, and if that's the holy grail in microchips these days then Poet just revealed that they have it. I guess the ring oscillator and 50 ghz Vcsel is just a proof of concept to those who don't know what Poet already knows it has.
