Microsoft and Asus partner on two new handheld consoles that combine the best bits of an Xbox with the latter's ROG Ally series of handhelds.

As in SteamOS, a traditional desktop UI will reportedly still be available on the ROG Xbox Ally, but you have to specifically decide to launch it. Hopefully, any version of this interface that also rolls out to generic Windows PCs would be able to save system resources by shutting off the traditional Windows UI entirely.
