Pixel Qi has shipped over 3 million displays in over fifteen laptop and tablet models; and XOs are becoming a minority of the worldwide usage of the robust low-power designs.

Their new displays continue to drop their power requirements; we would be able to save over half of the power our current displays draw by upgrading to the newest Qi design.  I have always loved this best of all of the tech innovations in the XO, and am delighted to see it take off as its own force for constructive change.
