Am I being too cynical when I say that the laptop you and I use will never be a 100% totally free. There will always be a blob on some sort in there. The most obvious one is the processor. With my naive knowledge of processor implementation, it's functionality is implemented in code more primitive than microcode. Is the source for this available for inspection?

There will be plenty of other devices in the laptop where its implementation domain is blurred.

Having said that, the Gluglug is a shuffle in the right direction.
