I wanted to follow up on this, because I stated at least twice in this thread that the Asus X205ma is powered by Micro USB. I was looking at the product's web page and it looks more like it's a square, reversible connector, not necessarily Micro USB. My apologies for that confusion. I have yet to see a formalized review of the Asus X205ma, which is now available at Best Buy and the Microsoft Store for $180, minus the benefit of the Office365 subscription. It looks like it may be available at Staples for $99 on Black Friday.

It would also appear I was wrong about the Stream 11 charger, meaning the Asus T100 is probably the closest you're going to come at this exact moment to a "full computer" that's charged via Micro USB.
