Do you see any ARM chips on the horizon this year or next that might change the equation? It looks like Amazon is seeing 40% better performance per watt (I think they said the power draw is comparable somewhere) with their custom design, will a commercially available chip be able to match that soon? Side note: Thanks for making a great product and keeping it cheap/free for hobby projects! I got comfortable with the basic features on a small project and now advocate for it's use regularly.
