To anyone who is considering this Ledger implementation to be a good idea, I would like them to (re)visit this topic started by dkbit98 about how the big brother wants to be able to crack your HW in the future.

Ledger not being fully open source and still being one of the most important HW providers would fit like a glove to those who seek to undermine the purpose of the HWs themselves. Be careful, the devil won't come to us with horns and in red, but dressed in white and offering "wonderful things".
