This might help answer some questions....?
Adafruit's "Ask an Engineer" show w/ guest Massimo Banzi. They start talking about Yun, and what's beneath the metal shield at around the 17 minute mark.
Thank you for linking this video!
Always interesting to see Massimo, although it doesn't give much details about the Linux hardware...
What I fear that with the excuse of providing a trendy "Cloud" access, the Arduino Yun is denying its Open Hardware roots
