It is very difficult to say what is never going to happen as opposed to what might realistically happen, but I still think that there's going to be a lot of change before Microsoft will start producing Android devices.

I am not saying it is impossible, just that it goes against the current business model they are trying to run. Hence, I honestly believe this is a hoax.
There existed prototypes for this kind of device, yes, but under the current organization they are never going to make it available to public.
