The one thing I don't understand about the Yun and Tre is...

Pierre7:
Sorry I am not the one who started this post. However am curious in learning about other micro controller products that are commercial or open source. I do like the arduino yet curious.

Commercial is commercial - automotive, appliances, toys, Internet devices and such.

"Open Source" implying "hobbyist" and development systems include (to a limited extent - the video is not fully Open Source) the Raspberry Pi, PIC/ Stamp, MSP430 and a couple of others less readily to mind.

JoeN:
I fully agree with you. But that the Arduino could use a "best of both worlds" component surely doesn't imply at all that it is the only application that could use such a component.

As I said before, this particular form of "twin processor" is really a developmental novelty, not something anyone generally needs in production as whatever the lesser chip (the AVR) does is then assimilated into the firmware of the more capable chip.
