[Discuss] Favorite OSHW Linux computers?

Recently I stumbled with one of these pseudo "open-source" boards. It was a
simple Arduino-Compatible GPS receiver. The manufacturer provides you with
all the schematics and documentation to make it work but the the firmware
is provided as a pre-compiled library.

The manufactured explained they made this desicion to reduce-costs and they
decided to use a cheap microcontroller that includes GPS signal-processing
capabilities but the manufacturer required them to sign a NDA for the
implementation details, so the source code is not available and simple
things like re-asign pin functions it's not possible because all is defined
in the precompiled library.

Sadly in the last year I have seen this is becoming s very common practice.
With software it's easy to compete because the cost of a whole FLOSS
implementation is zero and the main income comes from the
support/adaptation. But in OSHW you could face that using a
free/fully-documented/modular component/set of components increases your
manufacturing costs and another manufacturer could replicate the exact same
functionality using a cheaper-highly integrated but closed component.

However many of these manufacturers are using "Open-Source" (or using
Arduino-compatible as a synonim of it) to sell you essentially
closed-hardware. I think that the only thing that we can do is educate
people that even if they give you a detailed part list, if to build the
thing you require componentes under an NDA or there is missing source for
an important part of the implementation then that is not Open-Source
Hardware.

Regards,
Mario.
