find an Intel engineer that worked on it. There is a bigger story behind
it and I am not telling it.

And btw. it is perfectly fine that Intel is not giving full access to
their radios. Why should they?

I heard this all before and I don't buy it anymore. At some point the
companies in Asia will understand that the whole picture looks different
and that not always cheap, cheap, cheap is best for their margins.

And btw. the fully supported Linux hardware is in a lot of cases not
more expensive than the other ones.

You got one of the Greenphones ;)

I disagree here. They either play by the roles or they really do pay
Microsoft or go with BSD. I really couldn't care less.
