There seems to be a lot of confident talk about an Andromeda device, without any basis in fact or annoucement from Microsoft.
Yesterday on Windows Weekly it was suggested Andromeda as being a small mobile Windows based Note taking device.
But surely any mobile device, will require an mobile Apps ecosystem, and that excludes Windows as a platform. A mobile device without Apps, will not be acceptable to the buisness or consumer market. The only solution woud be an Android based device that would host OneNote and Android Apps the user wanted.
