Don't get me wrong, the Pi is a positive development, and I'm glad it exists. But I don't think that we should think of it as something with open source roots.

Don't get me wrong, the Pi is a positive development, and I'm glad it exists. But I don't think that we should think of it as something with open source roots. Sure, you're never going to get a 100% open device at these costs. But something like the BeagleBone Black is in the same price range as the Pi but doesn't have all of these issues (i.e., the lack of openness is not just due to pragmatic cost reasons, but also "because Broadcom".)
