Lenovo IdeaPad 1 is the one that I could find, but at the $350 price point needless to say it is not a flagship product. Main issue right now is that the 6W SoCs are about a generation and half behind the regular notebook APUs (which are themselves 0.5 to 1 generation behind the latest Zen in desktop CPUs). Not getting the latest and greatest means that it's highly unlikely anyone would want to bother designing a top-of-the-line product around it.

I'm fairly sure it is. Apple does have more experience with fanless SoCs though
