The "laptop" one with the flipout keyboard looks great.

I wasn't sure in the video - are these separate devices (large and small versions of the same thing)?

The laptop sized one would be awesome as a travel device if it were full-featured proper x86 device... I get the feeling these are android phones though right?

Edit: The larger device appears to be a "Surface Neo": https://www.microsoft.com/en-us/surface/devices/surface-neo

The marketing video for it has an Intel "CPU" animation so guessing this will be a "real" device?
