I can confirm that the MSRP for the Galileo is to be $60. This information comes from an Intel PR representative. Vendors may sell it for more or less than this, but the price makes this attractive to check it out and see if I might add Intel to the list of chips that I have worked with in the embedded world.
After I had submitted this story, it was announced that there is a new Arduino running a 1GHz TI Sitara. It would be interesting to run these two in a head to head to see which one actually came out on top.
